best star trek war episodes

The Top 57 Episodes of ‘Star Trek,’ Ranked From Great to Perfect

First, let’s be clear: Ranking the best “Star Trek” episodes is a silly thing to do. To date, the longest-running American TV franchise has aired a gargantuan 890 episodes and counting, starting with the original series in 1966. Since then, at least one “Star Trek” TV show has aired (or streamed) every decade, totaling 11 so far (with more on the way ). Choosing the best episodes within such a boundless, occasionally contradictory storytelling galaxy seems about as wise as cheating when playing poker with a Klingon.

On the other hand, there may be no more time-honored tradition among “Star Trek” fans than a vigorous debate over what constitutes the best of the franchise. (Best series ? Best captains ? Best starships ? Best aliens ? Best uniforms ? They’ve all been ranked multiple times !)

In that spirit — and to commemorate the 57th anniversary of “Star Trek” on Sept. 8 —  Variety ’s resident “Trek” geeks have ranked the top 57 episodes of all time, across the franchise.

Creating our list required some deep-dish nerdiness in its own right: We compiled a long list of episodes from each series that we felt deserved to be on the final ranking. Then we created our own individual rankings — and promptly realized our taste was quite divergent. To reconcile our lists, we adopted the approach of the great movie ranking podcast, Screen Drafts : We took alternating turns placing a pick from 57 to 1, and we each had two opportunities to veto the other’s pick (which in every case was to ensure it was placed higher on the list).

Other than the short-lived “Star Trek: The Animated Series” (1973-1974), this list reflects every other iteration of “Trek” on TV: “Star Trek: The Original Series” (1966-1969); “Star Trek: The Next Generation” (1987-1994); “Star Trek: Deep Space Nine” (1993-1999); “Star Trek: Voyager” (1995-2001); “Star Trek: Enterprise” (2001-2005); “Star Trek: Discovery” (2017-2024); “Star Trek: Picard” (2020-2023); “Star Trek: Prodigy” (2021-2022); and the ongoing “Star Trek: Lower Decks” (2020-present) and “Star Trek: Strange New Worlds” (2022-present).

The Way to Eden

“The Original Series” — Season 3, Episode 20

Look, this episode gets a lot of hate. But the fact is “TOS” is known (by today’s standards) for being very campy, and there is no episode campier than this one. A group of space hippies board the Enterprise on their journey to a mythical planet called Eden, where they can live happily forever. The episode memorably features Charles Napier (who would go on to a long career playing tough guys, villains, cops and the like) breaking out into song a bunch of times, including a jam session with Spock (Leonard Nimoy). —Joe Otterson Original airdate: Feb. 21, 1969

Terra Prime

“Enterprise” — Season 4, Episode 21 More than any other episode of “Enterprise,” “Terra Prime” made the most of the show’s mission to dramatize the beginnings of Starfleet, 100 years before the events of “TOS.” Just as a newfound coalition of planets begins to form on Earth (a precursor to the Federation), Captain Archer (Scott Bakula) and his crew must stop a xenophobic terrorist (played to the hilt by future “Star Trek Into Darkness” villain Peter Weller) bent on forcing all aliens to leave Earth. Subtle, it ain’t, but the story feels more relevant today than it did 20 years ago, and everyone in the cast gets a moment to shine. Alas, it came too late: “Enterprise” had been canceled before this episode even went into production. —Adam B. Vary Original airdate: May 13, 2005

“Prodigy” — Season 1, Episode 6

The animated “Prodigy” was the first “Star Trek” series geared toward kids, but that doesn’t mean there weren’t things for older “Trek” fans to enjoy. In particular, “Kobayashi” perfectly embodies what makes this show a worthy entry in “Trek” canon. Dal (Brett Gray) and Jankom Pog (Jason Mantzoukas) discover the holodeck aboard the Protostar, where they decide to go through the Kobayashi Maru, a.k.a. the “no-win scenario” that Capt. Kirk successfully beat during his time at the Academy. He gets help along the way from legendary characters like Spock, Dr. Crusher (Gates McFadden) and Odo (René Auberjonois). —J.O.

Original airdate: Jan. 6, 2022

Stormy Weather

“Discovery” — Season 4, Episode 6

On a mission to discover the origins of a cataclysmic gravitational anomaly, the U.S.S. Discovery enters a subspace rift and finds itself trapped inside a lethal black void that threatens to collapse in on the ship. The result is a classic race-against-time thriller (directed by “Trek” mainstay Jonathan Frakes), but what makes “Stormy Weather” stand out amid the heavily serialized episodes of “Discovery” is its emotionally resonant use of the ship’s sentient A.I. computer, Zora (Annabelle Wallis), who has to learn how to calm her mind from overwhelming stimuli in order to guide the ship out of danger. —A.B.V.

Original airdate: Dec. 23, 2021

Seventeen Seconds

“Picard” — Season 3, Episode 3

“Picard” didn’t find itself until Season 3, which reunited the core cast of “The Next Generation” — and it was really Episode 3 that sealed the deal. Riker (Frakes) is forced to take command of the Titan as Vadic (Amanda Plummer) and the Shrike hunt them. Picard (Patrick Stewart) and Dr. Crusher get an all-time great scene together as she reveals why she never told him about their son, Jack (Ed Speleers). Worf (Michael Dorn) makes his big return. We learn the Changelings are still intent on attacking the Federation. Riker and Picard end up at odds in a way we’ve never seen before. In short, epic. —J.O.

Original airdate: March 2, 2023

The Enemy Within

“The Original Series” — Season 1, Episode 5

The transporter — the cause of, and solution to, so many “Star Trek” problems — accidentally splits Capt. Kirk (William Shatner) into two people: Good Kirk, who is wracked with indecision, and evil Kirk, who is a histrionic asshole. Come for a meditation on the darkness that lies tucked inside everyone’s psyche, stay for some of William Shatner’s most deliciously hammy acting — and this was just the fifth episode of the series! —A.B.V.

Original airdate: Oct. 6, 1966

Family Business

“Deep Space Nine” — Season 3, Episode 23

The Ferengi episodes of “DS9” are always great comic relief, with this episode giving fans their first view of the home planet of Ferenginar and Ferengi culture in general. Quark (Armin Shimerman) and Rom (Max Grodénchik) must return home when their mother, Ishka (Andrea Martin), is accused of acquiring profit (gasp!), something Ferengi females are forbidden to do. Shimerman and Martin shine as they play out Quark and Ishka’s relationship, while Grodénchik really gets to put his comedic chops on display. This episode is also notable as the first appearance of Brunt (Jeffrey Combs) from the Ferengi Commerce Authority, as well as Kasidy Yates (Penny Johnson Jerald), frequent love interest of Cmdr. Sisko (Avery Brooks). —J.O.

Original airdate: May 15, 1995

Blink of an Eye

“Voyager” — Season 6, Episode 12

The Voyager gets stuck in orbit around a planet where time passes far more rapidly than in the rest of space, as the episode alternates between the bemused curiosity of Capt. Janeway (Kate Mulgrew) and her crew and the awestruck preoccupation of the expeditiously progressing populace on the planet below, for whom Voyager is a sparkling, fixed constant in the night sky. At one point, the Doctor (Robert Picard) beams down to the planet to investigate, and a delay of only a few minutes on Voyager means he spends three years on its surface. He even adopts a son! One of the great, wild what if? episodes of “Star Trek.” —A.B.V.

Original airdate: Jan. 19, 2000

“The Next Generation” — Season 3, Episode 23

Mark Lenard absolutely crushed the role of Spock’s father, Sarek, in multiple episodes across multiple “Star Trek” series and movies, but this episode is perhaps his finest performance as the character. Sarek comes to the Enterprise-D on what is meant to be his final mission, only for the crew to learn he is suffering from Bendii Syndrome. The condition leaves him prone to uncharacteristic emotional outbursts while also causing him to telepathically influence the emotions of those around him. Picard saves the day by mind melding with Sarek, allowing him to finish his mission with dignity — and provide Stewart with the chance for some powerhouse acting as he channels Sarek’s volcanic emotions. —J.O.

Original airdate: May 14, 1990

“Enterprise” — Season 3, Episode 10

“Trek” loves a moral dilemma, and this one’s a doozy: After Cmdr. Tucker (Connor Trinneer) is critically injured while the Enterprise is on a deep space mission, Dr. Phlox (John Billingsley) suggests growing a “mimetic symbiote” of Trip — effectively, a clone with a built-in two-week lifespan — in order to create the brain tissue needed to save Trip’s life. But that means the Enterprise crew must endure watching Trip’s clone rapidly age from a precocious kid to an adult man (played by Trinneer with eerie self-possession), who then pleads for his own right to live. Creepy and heartbreaking in equal measure. —A.B.V.

Original airdate: Nov. 19, 2003

Trials and Tribble-ations

“Deep Space Nine” — Season 5, Episode 6

This episode is a love letter to the original series, with the Defiant’s crew transported back in time to the events of “The Trouble With Tribbles.” A Klingon agent is planning to use a booby-trapped tribble to assassinate James T. Kirk. Thanks to digital editing, the crew is able to interact with the original Enterprise crew and keep the timeline intact. —J.O.

Original airdate: Nov. 4, 1996

“Deep Space Nine” — Season 2, Episode 23

Mirror universe episodes of “Star Trek” are (almost) always fun, if ultimately a little silly. But this one — in which Kira (Nana Visitor) and Dr. Bashir (Alexander Siddig) find themselves in an alternate reality in which Bajor, Cardassians and Klingons subjugate humans as slaves — comes closest to matching the spark of discovery in the original “TOS” episode. It’s especially fun to watch Visitor devour the role of Kira’s deliciously wicked mirror counterpart, the Intendant. —A.B.V.

Original airdate: May 16, 1994

Memento Mori

“Strange New Worlds” — Season 1, Episode 4

This episode proved “Strange New Worlds” — the newest “Star Trek” series — could be as action-packed as the very best of “Star Trek.” The Enterprise crew find themselves on the run from the Gorn, a savage enemy (first introduced on “TOS” and largely ignored in “Trek” canon) about which they know virtually nothing. They are forced to use every resource at their disposal to outwit and outrun the Gorn, including tapping into the subconscious of La’an (Christina Chong), the only crew member who has encountered the aliens and survived. —J.O.

Original airdate: May 26, 2022

Counterpoint

“Voyager” — Season 5, Episode 10

The main story is a tense, WWII allegory: Capt. Janeway and her crew hide telepathic refugees while passing through the space of the Devore, who have outlawed telepaths. But the real story is the relationship Janeway forms with the lead Devore inspector, Kashyk (Mark Harelik), who suddenly shows up alone and announces he’s defecting. As Kashyk aids Janeway in finding safe harbor for the refugees, she realizes how much he’s her intellectual equal, and she finds herself drawn to him — in spite of (or perhaps spurred on by) her continued suspicion of his motives. A great, subtle performance by Mulgrew captures both Janeway’s steely wits and her private yearning. —A.B.V.

Original airdate: Dec. 16, 1998

The Drumhead

“The Next Generation” — Season 4, Episode 21

“Star Trek” has done a number of courtroom episodes, and this is one of the best. Rear admiral Norah Satie (Jean Simmons) is sent to investigate suspected sabotage aboard the Enterprise. The investigation quickly spirals into paranoia and accusations of treachery against a crew member who is revealed to have Romulan lineage. It is an excellent reminder of what can happen when persecution is dressed up as an attempt at greater security, with Picard using Satie’s father’s teachings to bring about her downfall. —J.O.

Original airdate: April 29, 1991

“The Next Generation” — Season 7, Episode 8

More thwarted romance! The seasons-long will-they/won’t-they between Picard and Dr. Crusher (Gates McFadden) gets its best showcase, when the pair are captured by isolationist aliens and given implants that allow them to read each other’s thoughts. You get the feeling Stewart and especially McFadden had been dying to play out this dynamic on the show, so they both bring years of sublimated longing to the episode. —A.B.V.

Original airdate: Nov. 8, 1993

In the Hands of the Prophets

“Deep Space Nine” — Season 1, Episode 20

Louise Fletcher’s performance as Vedek Winn (later Kai Winn) ranks among the best “Star Trek” villains of all time. Deeply religious to the point of fanaticism, Winn protests Keiko O’Brien (Rosalind Chao) teaching children on Deep Space Nine that the wormhole aliens are not deities, as many Bajorans believe. Winn’s words whip Bajorans on the station into a frenzy; Keiko’s school is bombed. But what Winn really desires is power, to the point she tries to get one of her followers to kill a fellow Vedek she sees as a threat. The episode sets up Winn’s role as a major antagonist throughout the series to great effect. —J.O.

Original airdate: June 21, 1993

The Trouble With Tribbles

“The Original Series” — Season 2, Episode 15

If you’ve seen any episode of “TOS,” chances are it’s this one. While on shore leave at a space station, the Enterprise comes upon an adorably furry alien creature called a tribble, which are born pregnant, multiply exponentially, consume enormous quantities of food and react with alarm when in the presence of a Klingon. Fizzy and funny and, to this day, one of the best-known episodes of “Trek” ever. —A.B.V.

Original airdate: Dec. 29, 1967

Balance of Terror

“The Original Series” — Season 1, Episode 14

Introducing the Romulans alone makes this episode worthy of being on the list. But it’s also an epic cat-and-mouse game between Kirk and a Romulan commander played by none other than Mark Lenard, who would go on to play Sarek starting in Season 2. Kirk successfully lures the Romulan ship into a trap, leading to Lenard delivering the iconic line, “You and I are of a kind. In a different reality, I could have called you friend.” —J.O.

Original airdate: Dec. 15, 1966

“The Next Generation” — Season 4, Episode 20

John de Lancie never disappoints when he plays Q, but this episode offered a wonderful twist on his usual appearances. Following the events of “Deja Q,” Q returns to the Enterprise saying he owes Picard a debt. Picard repeatedly tells Q he wants nothing from him, but Q notices Picard has eyes for Vash (Jennifer Hetrick), the mercenary archeologist Picard first met on Risa. Being Q, he naturally transports Picard, Vash, and the bridge crew to a Robin Hood fantasy in which Picard must rescue Vash from the evil Sir Guy of Gisbourne (Clive Frevill). Added bonus: Worf, in scarlet tights, exclaiming in protest, “I am not a merry man!” —J.O.

Original airdate: April 22, 1991

“The Original Series” — Season 1, Episode 18

The classic “trial by combat” episode that pitted Kirk against a Gorn captain on a barren, rocky planet (i.e. the storied filming location Vasquez Rocks ). Few images from “Star Trek” have become more iconic than the original Gorn costume, which was essentially an actor dressed as a large lizard. The ending is also an all-timer, with Kirk choosing to spare the Gorn, proving to the all-powerful Metrons that set up the trial by combat that humans are capable of more than just random violence. —J.O.

Original airdate: Jan. 19, 1967

A Mathematically Perfect Redemption

“Lower Decks” — Season 3, Episode 7

“Star Trek’s” first pure comedy (and second animated series) often plays as a twisted love letter to the entire “Trek” franchise — like when Peanut Hamper (Kether Donohue), one of the sentient Exocomp robots first introduced on “The Next Generation,” abandons the crew of the U.S.S. Cerritos in a time of need. This episode tracks Peanut Hamper’s journey to redemption afterwards, which involves her encountering a seemingly primitive species called the Areore. To say anything more would spoil the fun; suffice it to say, “Trek” has rarely provoked gasps of deep laughter like this episode does. —A.B.V.

Original airdate: Oct. 6, 2022

Bar Association

“Deep Space Nine” — Season 4, Episode 15

What better episode of “Star Trek” to talk about after Hollywood’s hot labor summer? Fed up with the unfair conditions at Quark’s bar, Rom talks the other workers into forming a union and going on strike. Max Grodénchik truly shines in this episode as the would-be union leader. Once Rom successfully gets Quark to agree to all the workers’ demands, he outright quits and goes to work as a repair technician for the station, setting up some of Rom’s best moments in the episodes to come. —J.O.

Original airdate: Feb. 19, 1996

“Voyager” — Season 5, Episode 26 & Season 6, Episode 1

The Voyager swoops to the rescue of the Equinox, another Federation starship stranded in the Gamma Quadrant — only this one, led by Capt. Ransom (John Savage), is a smaller ship not meant for deep space travel. With their crew whittled down to just 12 people, Ransom has resorted to murdering alien creatures to use their bio-matter to boost the Equinox’s engines — a horrific violation of everything Starfleet stands for. The discovery pushes Janeway to her own limits, as she obsessively pursues the Equinox despite the cost to her own crew and her morality. The two-parter is one of the darkest episodes of “Star Trek,” a chilling reminder of how easily good people can find themselves slipping into disgrace. —A.B.V.

Original airdates: May 26, 1999 & Sept. 22, 1999

Who Mourns for Morn?

“Deep Space Nine” — Season 6, Episode 12

Morn (Mark Allen Shepherd) was a “Deep Space Nine” fixture, always at Quark’s bar, but never actually speaking onscreen. But in this episode, with Morn apparently dead in an accident, everyone reveals the offscreen times they spent with him, including the revelation that he “never shuts up.” Quark inherits all of Morn’s property, which Odo relishes revealing is ultimately nothing. But as it turns out, Morn had a much more adventurous life before his time on “DS9” than anyone knew, leading his former comrades to seek him out to get a hold of the money they believed he still possessed. —J.O.

Original airdate: Feb. 4, 1998

Species Ten-C

“Discovery” — Season 4, Episode 12

Other than the Gorn, almost all of the aliens on “Star Trek” are, essentially, humans with slightly different forehead ridges. But in its most recent season, “Discovery” embraced “Trek’s” prime directive (seeking out new life, bolding going where no one’s gone, etc.) by crafting a species that is truly alien: the Ten-C. Throughout the season, the Ten-C are presented as both a total mystery and an existential threat; when Capt. Burnham (Sonequa Martin-Green) and the crew of the Discovery finally reach them — outside the barrier of the Milky Way galaxy — they are unlike anything the show has ever encountered. Rarely has “Trek” applied more intellectual and emotional rigor to what it might actually be like to attempt first contact with extra-terrestrials, and rarely has it been this compelling. —A.B.V.

Original airdate: March 10, 2022

A Man Alone

“Deep Space Nine” — Season 1, Episode 4

Odo is one of the best characters in “DS9” — and in the “Star Trek” universe — in general, and this is the first episode to really establish him as a standout . A known criminal returns to the station only to die shortly after, and Odo is accused of his murder. Odo’s status as an outsider, but ultimately someone to be respected, is made crystal clear in this episode, with even his archenemy Quark acknowledging that Odo is not the type to murder someone in cold blood. —J.O.

Original airdate: Jan. 17, 1993

Mirror, Mirror

“The Original Series” — Season 2, Episode 4

The transporter strikes again, this time accidentally zapping Kirk, Uhura (Nichelle Nichols), Scotty (James Doohan) and Bones (DeForest Kelley) from their reality into a parallel universe in which the benevolent Federation has been replaced by the bloodthirsty Terran Empire, governed by brute force and fascistic exploitation — and Spock has a goatee! More silly than serious (and no less fun for it), the episode effectively spawned an entire sub-genre of parallel universe episodes of TV (from “Supernatural” to “Friends”) and gave generations of actors a chance to play wildly against type. —A.B.V.

Original airdate: Oct. 6, 1967

“The Next Generation” — Season 4, Episode 2

People rave about “The Best of Both Worlds” and Picard’s assimilation by the Borg, but fewer remember this incredible follow-up episode. Picard returns to his family vineyard to put the Borg incident behind him, even briefly thinking that he will leave Starfleet. Jeremy Kemp crushes it as Picard’s brother Robert, with the two sharing a memorable (and muddy) scene in which Picard breaks down and admits how much his assimilation has shaken him. The episode is also memorable for the appearance of Worf’s adoptive parents, who come to the Enterprise to be with him following his discommendation. —J.O.

Original airdate: Oct. 1, 1990

Living Witness

“Voyager” — Season 4, Episode 23

For several minutes, “Living Witness” seems like a mirror universe episode, as a ruthless Janeway, captain of the “warship” Voyager, agrees to aid the Vaskans against the insurgent Kyrians by unleashing a biological weapon upon millions and executing the Kyrian leader. But then we realize that we’ve just witnessed a recreation at a Kyrian museum 700 years in the future, at which point a copy of the Doctor enters the story and learns, to his horror, how much the Kyrians have gotten wrong. What could have been a Rashomon-style caper instead becomes fascinating meditation on how the telling of history can be weaponized, even inadvertently, to maintain old wounds rather than heal them. —A.B.V.

Original airdate: April 29, 1998

Unification

“The Next Generation” — Season 5, Episode 7 & 8

Spock appeared on “The Next Generation” a month before the release of 1991’s “Star Trek VI: The Undiscovered Country” — but this time, at least, crass cross-promotion prompted some sublimely entertaining TV, as Picard and Data (Brent Spiner) aid Spock in his effort to reunify the Romulan and Vulcan peoples. [Stefon voice]: This two-parter has everything : Klingon warbirds, rude Ferengis, Tasha’s evil Romulan daughter Sela (Denise Crosby), Data and Spock philosophizing on their twin pursuits of logic and emotion, the death of Sarek, Worf singing Klingon opera with a four-armed bar pianist, and Picard and Spock mind-melding! —A.B.V.

Original airdates: Nov. 4 & 11, 1991

“Deep Space Nine” — Season 7, Episode 9

Gul Dukat is the best villain in “Star Trek.” Yes, you read that right. The writers and actor Marc Alaimo created an incredibly nuanced character that goes through a remarkable arc over the course of the series. This episode, near the end of “DS9’s” run, reminds fans that Dukat sees himself as a savior, but is ultimately a force for evil. He establishes a cult dedicated to the Pah wraiths on Empok Nor, luring a number of Bajorans to his side. But of course, he also sleeps with his female followers and tries to trick them into a mass suicide. Amazing stuff. —J.O.

Original airdate: Nov. 23, 1998

The Last Generation

“Picard” — Season 3, Episode 10

The cast of “TNG” infamously never got their swan song, after 2002’s “Star Trek: Nemesis” bombed in theaters, so this series finale serves as a gift both to them and to “TNG” fans. Every character gets their spotlight, including the resurrected Enterprise-D, as Picard, Riker, Dr. Crusher, Data, Worf, LaForge (LeVar Burton) and Troi (Marina Sirtis) all help to take down the Borg once and for all. The final scene — everyone sitting around a poker table, laughing and reminiscing — is as pure and satisfying an expression of fan service as anything “Trek” has ever done. —A.B.V.

Original airdate: April 20, 2023

“The Next Generation” — Season 3, Episode 13

Until this episode, Q was an enjoyably malevolent force within “TNG,” an omnipotent being who’d gleefully pop up now and again to play with the lives of the Enterprise-D crew. But here, when Q suddenly appears on the bridge, he’s been stripped of all his powers (and all of his clothes) and begs Picard for safe harbor. At first, no one believes him — even after Guinan (Whoopi Goldberg) stabs him with a fork — which only fuels John de Lancie’s sparkling performance, as Q confronts life as ( shudder ) a mortal human. —A.B.V.

Original airdate: Feb. 3, 1990

An Embarrassment of Dooplers

“Lower Decks” — Season 2, Episode 5

The title refers to an alien called a Doopler, who duplicate themselves whenever they get embarrassed — which, naturally, becomes an issue the moment one steps foot on the Cerritos. But really, this episode is one of those deeply enjoyable “Trek” episodes that is less about story than it is about the vibes , as the characters spend their downtime winningly contending with the central premise of the show: The bittersweet contentment of life at the bottom of the ladder. —A.B.V.

Original airdate: Sept. 9, 2021

“Deep Space Nine” — Season 2, Episode 19    

The lives of the past hosts of the Dax symbiont are a recurring plot device on “DS9,” and no episode does it better than this one. A group of Klingons who knew Curzon Dax arrive at the station and enlist Jadzia’s (Terry Ferrell) help in killing their sworn enemy, a criminal known as The Albino who killed the three Klingons’ first-born sons. Jadzia ultimately honors the blood oath, as the episode explores the meaning of honor and solidarity. —J.O.

Original airdate: March 28, 1994

Where No Man Has Gone Before

“The Original Series” — Season 1, Episode 3

The famed second pilot episode of “Star Trek” (which introduced William Shatner as Capt. Kirk) is a strange artifact today: Bones and Uhura aren’t aboard yet, Sulu (George Takei) isn’t at the helm, the Enterprise has a psychiatrist (played by Sally Kellerman), and the uniforms and sets look a bit off. But the central story — Kirk’s best friend, Gary Mitchell (Gary Lockwood), is zapped by an energy blast at the edge of the galaxy, and begins to exhibit extraordinary psychokinetic powers — is vintage “Trek”: Brainy, brawny, and just the right side of uncanny. And it’s fascinating now to see how well-established Kirk and Spock’s dynamic of emotion vs. logic was from the very start. —A.B.V.

Original airdate: Sept. 22, 1966

The Measure of a Man

“The Next Generation” — Season 2, Episode 9

Data’s quest for humanity is at the very core of “TNG,” and this stirring episode literally puts that quest on trial — and establishes the show’s voice for the rest of its run. A Starfleet scientist wants to dismantle Data in order to create more androids, but Data refuses, setting up an intense courtroom drama — is Data merely a machine and the property of Starfleet? — with Picard representing Data while Riker is forced to represent the scientist. —J.O.

Original airdate: Feb. 13, 1989

“The Next Generation” — Season 4, Episode 26 & Season 5, Episode 1

The Klingons started on “Trek” as a not-that-thinly-veiled metaphor for the Soviet Union at the height of the Cold War, but over the decades, they’ve developed their own richly detailed mythology. This two-parter (which aired just before the fall of the USSR) depicts a civil war within the Klingon Empire that leads to Worf’s decision to leave the Enterprise and join the fight. For a series that was episodic by design, this is the closest “TNG” ever got to serialized storytelling, incorporating events from several previous episodes — including the shocking introduction of Tasha’s Romulan daughter, Sela. —A.B.V.

Original airdates: June 17, 1991 & Sept. 23, 1991

“Deep Space Nine” — Season 1, Episode 11

It is endlessly entertaining to see Quark get what he wants as he then  learns that it’s way more trouble than he realized. This episode sums that idea up nicely, while also featuring the first of many wonderful appearances by Wallace Shawn as Ferengi leader Grand Nagus Zek. Zek unexpectedly names Quark his successor, only for Zek to die shortly after. Quark is thrilled at first, before he realizes being the Nagus puts a massive target on his back. This episode also helps build the friendship between Nog (Aron Eisenbeg) and Jake (Cirroc Lofton), with Jake secretly teaching Nog how to read. —J.O.

Original airdate: March 22, 1993

Tinker, Tenor, Doctor, Spy

“Voyager” — Season 6, Episode 4

Yearning to grow past his programming, the Doctor allows himself the ability to daydream, in one of the flat-out funniest episodes of “Trek” ever. It opens with Robert Picardo singing opera as Tuvok (Tim Russ) undergoes pon farr (i.e. the madness to mate that consumes Vulcan males) and just gets wilder from there, up to the moment when the Doctor, who’d fantasized about taking over command of Voyager in an emergency, does it for real. —A.B.V.

Original airdate: Oct. 13, 1999

“The Original Series” — Season 2, Episode 1

Speaking of pon farr, this is the “TOS” episode that first establishes it — as well as the planet Vulcan, several Vulcan customs and traditions, and the now legendary Vulcan salute (honorable mention: Spock actually smiles!). Wracked with pon farr, Spock asks for leave back on his home planet, and eventually reveals that he must meet his betrothed, T’Pring (Arlene Martel). Naturally, Kirk and Spock end up in a fight to the death in one of the most iconic battles in “Star Trek” history. —J.O.

Original airdate: Sept. 15, 1967

Year of Hell

“Voyager” — Season 4, Episode 8 & 9

The most lasting criticism of “Voyager” is that every week, no matter what happened in the previous episode, the ship and crew emerged unscathed and ready for a new adventure. As if in response, this two-parter tracks a year in which the Voyager is ravaged to the point of near ruin by repeated encounters with an aggressive alien species called the Krenim. Unbeknownst to the crew, they’re actually the victims of a Krenim scientist, Annorax (Kurtwood Smith), who developed a technology to alter the fabric of time by erasing entire species from ever existing. This is as harrowing and merciless as “Trek’s” ever been, but it’s not quite the best episode of “Voyager” due to the irony of its ending: Janeway crashes the husk of the Voyager into Annorax’s timeship — which resets the timeline completely, as if nothing that we’d seen had ever happened. —A.B.V.

“Deep Space Nine” — Season 3, Episodes 11 & 12

“Star Trek” often addresses timely societal issues, but this episode put them firmly in a 21st century context. Sisko, Bashir, and Dax accidentally wind up in San Francisco circa 2024, where poverty and oppression of the disadvantaged are running rampant (crazy how that remains timely, huh?). When a man meant to serve an important purpose in an historic riot is accidentally killed too soon, Sisko is forced to take his place. —J.O.

Original airdate: Jan. 2, 1995 & Jan. 9, 1995

Those Old Scientists

“Strange New Worlds” — Season 2, Episode 7

In one of the rare “Trek” crossover episodes, Ens. Boimler (Jack Quaid) and Ens. Mariner (Tawny Newsome) from “Lower Decks” find themselves zapped back to the era when Capt. Pike (Anson Mount) captained the Enterprise. Marshalled by Jonathan Frakes’ steady hand as a director , the disparate tones of “Lower Decks” and “Strange New World” somehow mesh perfectly, and hilariously, together. Packed with guffaw-worthy laughs, “Those Old Scientists” also becomes a deeply poignant expression of the impact “Trek” has had on generations of fans. Maybe it’s controversial to place one of the most recent “Trek” episodes so high on this list, but this one more than earns its spot. —A.B.V.

Original airdate: July 22, 2023

The Best of Both Worlds

“The Next Generation” — Season 3, Episode 26 & Season 4, Episode 1

This two-parter is frequently cited as the best “Next Generation” storyline of all time, mostly because it features one of the most iconic cliffhangers in all of television. The Borg attack the Federation, leading to a showdown with the Enterprise. Picard is captured and assimilated, revealing himself to his crew as Locutus of Borg. If we’re splitting Borg nano-probes, the second half doesn’t quite live up to the first, which is why, for us, it doesn’t quite rank into the Top 10. Special shoutout to this episode for setting up the incredible “Star Trek” film “First Contact.” —J.O.

Original airdate: June 18, 1990 & Sept. 24, 1990

“Deep Space Nine” — Season 1, Episode 19

When a Cardassian named Marritza (Harris Yulin) arrives on Deep Space Nine, Kira realizes he must have worked at one of the most notorious labor camps during Cardassia’s occupation of Bajor, and she arrests him as a war criminal. What follows is effectively a two-hander, as Kira’s interrogation of Marritza leads to a series of revelations that unmoor her hard-won fury at the atrocities inflicted upon her people. The conventional wisdom is that “DS9” didn’t get cooking until the Dominion War, but this early episode proves that this show was providing great, searing drama from the start. —A.B.V.

Original airdate: June 14, 1993

“The Original Series” — Season 1, Episode 22

Ricardo Montalbán makes his debut as Khan Noonien Singh, a genetically superior dictator from Earth’s Eugenics Wars. Khan and his people have been in suspended animation for 200 years and are looking to dominate humanity once again. Naturally, Kirk is able to beat Khan in a riveting confrontation, but rather than send him and his people to a penal colony, he agrees to let them settle on the wild planet, Ceti Alpha V. The episode proved to be so good, it led to the 1982 film “Star Trek II: Wrath of Khan,” arguably the best “Trek” movie of all time. —J.O.

Original airdate: Feb. 16, 1967

“Voyager” — Season 5, Episode 6

There’s something about time travel — and the twisty narrative paradoxes it can cause — that has engendered some of the best episodes of “Trek” ever made. That certainly includes this stunning “Voyager” episode, which opens with Harry Kim (Garrett Wang) and Chakotay (Robert Beltran), 15 years in the future, discovering the frozen husk of the Voyager buried inside a glacier on a barren ice planet. It turns out Kim made a critical mistake that caused the catastrophic accident, from which only he and Chakotay survived. Their unyielding fixation to right that wrong — and erase the previous 15 years from history — makes for a gripping nail-biter about regret and devotion. Not only did LeVar Burton direct, but he cameos as Capt. Geordi La Forge! —A.B.V.

Original airdate: Nov. 18, 1998

The Defector

“The Next Generation” — Season 3, Episode 10

Did a Romulan admiral really defect to the Federation, or are the Romulans perpetrating an elaborate hoax on Picard and the Enterprise crew? This wonderful episode sees the admiral in question (played by James Sloyan) claiming the Romulans are building a secret base within the Neutral Zone, forcing Picard to consider whether or not he should investigate and thus risk starting a war. It also features the excellent opening in which Picard tries to teach Data about humanity by having him act out scenes from Shakespeare’s “Henry V.” —J.O.

Original airdate: Jan. 1, 1990

Chain of Command

“The Next Generation” — Season 6, Episode 10 & 11

Lured into Cardassian territory under false pretenses, Picard is captured and systematically tortured by a ruthless interrogator, Gul Madred, in a chilling performance by David Warner. Their disturbing tête-à-tête — Picard is stripped naked and nearly broken by the end — would be enough for one of the all-time best “Trek” episodes. But this two-parter also boasts Ronny Cox as Capt. Jellico, Picard’s replacement on the Enterprise, whose prickly and demanding leadership style creates all kinds of thrilling friction among the crew. —A.B.V.

Original airdates: Dec. 14 & 21, 1992

In the Pale Moonlight

“Deep Space Nine” — Season 6, Episode 19

In this fantastic episode, Sisko grapples with the ethics of doing whatever it takes to get the Romulans to join the Dominion War on the Federation-Klingon side. This includes falsifying evidence and freeing a known criminal from Klingon prison with the help of master spy Garak (played by the always wonderful Andrew Robinson). Sisko (while recording a personal log) delivers a series of powerful monologues direct to camera about why he did what he did, ultimately deciding it was worth it in the end. —J.O.

Original airdate: April 13, 1998

The City on the Edge of Forever

“The Original Series” — Season 1, Episode 28

Accidentally hopped up on stimulants, a crazed Bones leaps through a time portal on an alien planet and winds up changing history so drastically that the Enterprise disappears. Kirk and Spock travel back to stop him, and land in New York City during the Great Depression, where they learn that Bones saved the life of Sister Edith Keeler (Joan Collins), a pacifist whose message resonates so strongly that the U.S. stays out of WWII, allowing the Nazis to conquer Europe. Alas, Kirk falls deeply in love with Keeler, establishing a classic “Trek” moral dilemma: How does one suppress their most profound personal feelings for the greater good? An all-timer that still resonates today. —A.B.V.

Original airdate: April 6, 1967

Far Beyond the Stars

“Deep Space Nine” — Season 6, Episode 13

In this Avery Brooks-directed episode, Sisko envisions himself as a Black science fiction writer in 1950s New York named Benny Russell. Russell dreams up a story about the crew of a space station led by a Black captain, but his publisher refuses to run it. This episode is memorable for many reasons, the biggest of which being its handling of racism, but it also allows the show’s main cast gets to appear without any prosthetics or makeup, as completely different characters, to great effect. —J.O.

Original airdate: Feb. 9, 1998

Yesterday’s Enterprise

“The Next Generation” — Season 3, Episode 15

The Enterprise-C, believed to have been destroyed over 20 years earlier, emerges from a temporal anomaly and resets history into a decades-long war between the Federation and the Klingon Empire. Tasha — killed off in Season 1 (after Denise Crosby wanted to leave the show) — is brought back to life, and falls for the Enterprise-C’s helmsman (Christopher McDonald), while Guinan implores Picard that something is desperately wrong with history and he must send the Enterprise-C back to certain doom. Somehow, this episode crams a movie’s worth of story into a nimble and rousing 44 minutes. Not a second is wasted. Outrageously great. —A.B.V.

Original airdate: Feb. 19, 1990

The Inner Light

“The Next Generation” — Season 5, Episode 25

When the Enterprise comes upon a mysterious probe, Picard is suddenly hit with a signal that plunges him into a different man’s life on a dying planet. There, Picard experiences half a lifetime, with a wife, children and grandchildren, all in the space of 25 minutes. When Picard realizes this was all meant as a time capsule — a way to preserve the stories of the people of the planet, which was destroyed 1,000 years earlier by an exploding star — the revelation that he lived the life he’d long forsaken as a Starfleet captain, only to have it ripped away, is almost more than he can bear. But hoo boy, does it make for stunning, deeply moving television. In fact, almost no episode of “Trek” is better. Almost. —A.B.V.

Original airdate: June 1, 1992

The Visitor

“Deep Space Nine” — Season 4, Episode 2

Don’t watch this one without tissues handy. This emotionally devastating episode gets right to the heart of what made “DS9” so special — the relationship between Sisko and his son, Jake. Told in flashbacks by an elderly Jake (Tony Todd), the episode recounts how Sisko became unstuck in time, briefly revisiting Jake over the course of his life, and how Jake is determined to bring him back. In brief, fleeting moments, Sisko tells Jake not to worry about him and to live his life to the fullest. But Jake cannot bear the thought of losing his father forever, ultimately sacrificing his own life to restore the normal flow of time. —J.O.

The 20 Best Episodes of ‘Star Trek: The Original Series’

If you’re looking to get into the ‘Trek’ that started it all, start here.

In the more than 50 years since Star Trek made its debut on NBC, the franchise has seen more than a dozen feature films and successfully launched its sixth spinoff series last year with CBS All Access’ Star Trek: Discovery . For all the many amazing stories told in the decades to come, it’s hard to beat the original Star Trek . Running for just three seasons, the series has become synonymous with the science fiction genre and emerged a cultural touchstone that has entertained, educated and inspired dreamers all over the world.

Like any series, Star Trek has its ups and downs. The best episodes, though, rank among television’s very finest. We’ve assembled a list of Star Trek ’s 20 best original series episodes, each of which has withstood the test of time in delivering stories that, despite their spectacle and imagination, are ultimately about exploring the human condition. As such, many of the themes explored on Gene Roddenberry ’s show have only become more relevant and the show’s 23 rd century setting all the more important a future to which we might aspire.

20) The Menagerie - Parts One and Two

The only two-part episode of the original Star Trek , “The Menagerie” is, in a weird way, a kind of clip show. Before William Shatner was cast as Captain James T. Kirk, Star Trek had shot a pilot, “The Cage,” starring Jeffrey Hunter as Captain Christopher Pike. In fact, the only character to carry over from the unaired pilot was Leonard Nimoy’s Spock. Naturally, he’s front and center of “The Menagerie,” a Starfleet courtroom drama in which Enterprise logs are used as evidence, allowing the entirety of “The Cage” to be incorporated into a larger story set some years later.

Hunter did not reprise the Pike role, the episode finding the character having just suffered an accident that has left him a scarred shell of his former self. With a mysterious motivation that is revealed through the course of his trial, Spock abducts Pike and commandeers the Enterprise. With a course locked to a forbidden planet, Spock calmly turns himself over for his court martial, giving the narrative a fantastic ticking clock.

“The Menagerie” arrived midway through Star Trek’s first season and its expansion of Star Trek lore is, in part, why the franchise continues to this day. Bringing “The Cage” (released some years later on its own) into Star Trek continuity paved the way for future Captains of the Enterprise and reminded us that Star Trek’s timeline doesn’t necessarily need to proceed linearly.

Anyone familiar with Star Trek from the J.J. Abrams films also got to meet Captain Pike. Bruce Greenwood played the part in both 2009’s Star Trek and 2013’s Star Trek Into Darkness .

19) The Corbomite Maneuver

Although it aired out of sequence, “The Corbomite Maneuever” followed Star Trek ’s first two pilots with a story that sees the Enterprise coming into contact with a mysterious and powerful alien sphere in an unexplored area of space. Diplomacy soon fails and a strange looking creature, Balok, tells Kirk that his ship will be destroyed. That’s when Kirk comes up with an epic bluff, aiming to convince the alien that the Enterprise contains a made up element, corbomite, that promises mutually assured destruction.

The notion of bluffing is huge in Star Trek and “The Corbomite Manuever” is the most classic example. A bluff, after all, means applying fiction to create a better reality. In a nutshell, that’s exactly what Star Trek is all about. Over the course of the series, the crew of the Enterprise will use their unique perspective to defy the laws of alien civilizations, Starfleet’s own bureaucracy and even of physics themselves. It’s usually about knowing the right time to do the wrong thing and, of that, Captain Kirk is a proven master. He knows exactly when to bend the rules to achieve the greater good.

“The Corbomite Maneuver” also introduces a common theme that alien races aren’t necessarily as alien as they might appear with a final act that features a young Clint Howard .

18) A Piece of the Action

It may sound a bit silly, but the Enterprise’s visit to a planet ruled by 1920’s Chicago gangsters is a whole lot of fun. It even makes a bit more sense than it sounds: a hundred years before this episode takes place, another ship, the Horizon, wound up bringing a book about Chicago mobsters to the planet’s highly suggestible inhabitants, the Iotians. Treating it like a bible, the entire culture adapted to suit the book.

There’s a lot of costume play throughout Star Trek history and seeing Kirk and Spock in gangster outfits is a whole lot more fun than say, the time they have to dress up the Nazis in the second season episode “Patterns of Force”. “A Piece of the Action” would serve as a prototype for Star Trek: The Next Generation ’s holodeck episodes and open the idea that any planet anywhere in the universe could theoretically have a culture identical to any period on Earth.

An abandoned plotline for a 30 th anniversary episode of Star Trek: Deep Space Nine (later told in alternate form in a Star Trek comic) would have seen a return to the Iotian planet and the reveal that, following the events of “A Piece of the Action,” the planet wound up being so heavily influenced by the Enterprise’s visit that it had evolved to become, essentially, a planet of classic Star Trek fans.

17) The Squire of Gothos

Several episodes of the original Star Trek find the crew coming face to face with seemingly omnipotent foes, but few are as quite as memorable as William Campbell ’s performance as the ebullient mischief maker Trelane, self-professed “Squire of Gothos”. When the Enterprise discovers a planet in an area of space that should be abandoned, the crew is drawn to the world’s sole inhabitant, a godlike individual fascinated with 18 th century Earth history who views the crew as nothing more than his playthings.

From Loki of Greek mythology to DC Comics’ Mr. Mxyzptlk, the trickster god is a classic foe. Part of what makes it work so well in the world of Star Trek is because the crew of the Enterprise, to us, appears so advanced technologically. As was the case with foes like Thor or Superman, having an even more powerful foes forces the heroes to rely on their wits alone, ultimately proving that omnipotence is nothing without intelligence and compassion.

Trelane also helped pave the way for John DeLancie ’s Q on Star Trek: The Next Generation . Appearing in more than a dozen episodes of subsequent Star Trek series, Q shares Trelane’s paradoxical blend affability and obnoxiousness. While it’s never specified in the canon, stories told in Star Trek books and comics have connected the characters.

16) Day of the Dove

The Enterprise responds to a distress call only to find a deserted planet and Klingon forces nearby. When both ships somehow become disabled, tensions begin to mount to an unusual degree. Walter Koenig ’s Chekov is threatening to avenge the death of his brother at the Klingons’ hands. But then it’s revealed that he doesn’t even have a brother. Things get weirder and weirder as the planet itself seems to encourage conflict, supplying weapons and easy reasons to give into hatred.

It’s never revealed exactly what the force is that both crews encounter on planet Beta XII-A, but it seems to be a destructive energy that is, perhaps, a manifestation of destructive energy itself, depicted as a crackling red force. When Kirk realizes that he and Michael Ansara ’s Klingon commander Kang are being manipulated, “Day of the Dove” gives us one of William Shatner ’s great mini-monologues.

“All right. All right,” Kirk shouts at Kang. “In the heart. In the head. I won't stay dead. Next time I'll do the same to you. I'll kill you. And it goes on, the good old game of war, pawn against pawn! Stopping the bad guys. While somewhere, something sits back and laughs and starts it all over again.”

That’s a message that, sadly, is every bit as timely today as it was half a century ago.

15) The Galileo Seven

Things go bad during a routine science mission, forcing a shuttlecraft, the Galileo, to make an emergency landing on a dangerous planet, home to enormous apelike beasts. What’s more, a coming ion storm and trouble in another part of the galaxy mean that the Enterprise may need to give up the search.

While there’s some great Kirk moments as he squeezes every possible opportunity from the chain of command to keep looking for the Galileo, this episode is Spock’s show. We get to see him take command over a six-person crew and deal with having to give orders that put officers in mortal danger. Fear amongst the crew makes things all the more dangerous as Spock has to face officers who question his Vulcan logic and, ultimately, his own uncertainty in command to save the crew.

The plot for “The Galileo Seven” originated with Oliver Crawford , who co-wrote the episode’s script with S. Bar-David . He has said that “The Galileo Seven” was directly inspired by the 1939 big screen thriller Five Came Back , about a small airplane that crashed in a South American jungle.

14) A Private Little War

Star Trek was offering a direct allegorical take on the Vietnam War in 1968 with a story that finds Captain Kirk in a moral dilemma. A planet of immense natural resources, Neural, is home to a primitive race. Although Starfleet’s Prime Directive would normally preclude any interference, the Enterprise learns that conflict has broken out among the natives with one side being given advanced weaponry by the Klingon Empire.

While the Enterprise quite often finds itself in the position of having to balance moral imperatives, “A Private Little War” is the best example of the show taking on a contemporary political issue, even if the conclusion doesn’t offer any easy answers.

“A Private Little War” also introduces a memorable Star Trek alien that only appears in this one episode. The Mugato is a ferocious white ape with a spiked back and a poisonous bite. Ben Stiller , a big Star Trek fan, borrowed the name for Will Ferrell ’s character in his 2001 comedy Zoolander .

13) Journey to Babel

The Enterprise is journeying to the planet Babel for a diplomatic conference when one of the visiting ambassadors is murdered. The lineup of suspects includes a wide range of alien dignitaries and one chief suspect: Mark Lenard ’s Vulcan ambassador Sarek. Adding to the drama, Sarek just happens to be Spock’s estranged father.

Not only is “Journey to Babel” an interesting mystery with a grand assembly of interesting alien species, it reveals so much about Spock and his history with his father. It’s a relationship that continues to develop for decades after “Journey to Babel”. Lenard returns as Sarek throughout the franchise’s big screen run and beyond. He’s even set to be a featured character in Star Trek: Discovery with James Frain filling in for the late Lenard.

Before he played Sarek, Mark Lenard famously took on the role of another prominent Star Trek character. Look for details on that performance a bit further down this list.

12) Let That Be Your Last Battlefield

The Enterprise intercepts a stolen shuttlecraft containing Lou Antonio’s Lokai, a fugitive from a planet called Charon. Although he looks like a human being, Lokai is split down the middle, one side black and the other white. It’s not long before Frank Gorshin shows up as Bele, a fellow being from Charon who utterly despises Lokai. Although they may initially appear identical, it is revealed that Bele and Lokai are alternately colored. Bele is black on the left side and white on the right while Lokai is the reverse. Hence, in their culture, their hatred for one another.

With “Let That Be Your Last Battlefield,” Star Trek finds a way to tell a story that isn’t just about racism, but that makes racism itself the focal point for its sci-fi lens, imagining a brand new way to hate and making a powerful reminder that any reason for doing so based on any other physical attribute is just as unnatural.

11) The Doomsday Machine

The crew of the Enterprise faces one of its most awesome cosmic challenges when it comes up against a massive, world-eating device of extreme alien origin. In fact, the device is so alien that we never really learn what it is, although Kirk theorizes it to be an ancient doomsday device. The Enterprise isn’t the first Starfleet ship on the scene this time, either. By the time the Enterprise discovers the danger to the galaxy, the USS Constellation has already risked everything in an attempt to stop the planet killer. The Constellation is recovered by the Enterprise with only one crewmember still left alive, William Windom ’s Commodore Matt Decker.

Not only does “The Doomsday Machine” feature such a memorable monster, it features some great drama between Kirk and Decker. Having just lost his crew to the cosmic goliath, the Commodore is suffering from severe posttraumatic stress and not necessarily thinking with a clear head. Because he technically outranks Kirk, that poses a serious problem in dealing with the matter at hand.

“The Doomsday Machine” also sets up a nice bit of continuity with Star Trek: The Motion Picture . One of the main characters in the 1979 Robert Wise film is Stephen Collins ’ Captain Willard Decker, the son of Commodore Matt Decker.

10) The Devil in the Dark

Something is killing workers on distant a mining colony visited by the Enterprise. Deep in the caves of Janus VI, a rocklike creature is melting people alive with its molten abilities. Despite the attacks, though, there’s no trace of the creature and no understanding for how a carbon based life form could exist in such an environment.

“The Devil in the Dark” functions as both a sci-fi slasher and a moral tale. The end of the episode reveals that life sometimes manifests itself in forms that we may not have ever considered, brought to life visually when Spock performs a Vulcan mind-meld with the alien creature, a horta, and learns that its motivations are not malicious and that, instead, it is the miners who have unwittingly done a great wrong to it.

Although the horta marks another iconic Star Trek alien, “The Devil in the Dark” is their sole appearance of the species the franchise outside of very minor nods in later spinoffs.

9) By Any Other Name

The Enterprise encounters a pair of scouts from the Kelvan Empire, mighty beings from the Andromeda Galaxy who want to use the Starfleet vessel on a generational voyage to their homeworld. Armed with powerful belts that can, among other things, transform people into easily destroyed little polyhedrons of their basic genetic makeup, they easily take the ship. Only a few officers are left in their human form and it’s humanity that, as it often does, gives the Enterprise crew their edge. Because the Kelvans have taken human form for their journey, they’re not used to some of the finer points of being human.

“By Any Other Name” has James Doohan ’s Scotty teaching the male Kelvan about alcohol while Kirk teaches the female one about love. There’s a major degree to which Star Trek celebrates the clash of human and alien cultures and here we get to see the whole crew doing so to the best of their specific abilities.

The work of William Shakespeare is something referenced quite a bit throughout the Star Trek franchise. This episode references a line in Romeo and Juliet wherein Juliet argues that a rose is a rose because of the form it takes and not what it’s called.  Star Trek expands that idea with the suggestion that anything in the form of mankind will, in doing so, become mankind.

8) A Taste of Armageddon

“A Taste of Armageddon” offers a brilliantly high concept sci-fi plot: the Enterprise visits a world that has evolved beyond destructive combat, but not beyond war itself. Instead of destroying one another with weapons that would threaten to also destroy their culture, the conflicting sides of Eminiar VII’s population have agreed to wage war through a highly accurate simulation. If a resident is in an area that the simulation has deemed destroyed, he or she is expected to immediately turn themselves in for disintegration. Unfortunately, a few Enterprise crewmembers are unwittingly present when a building is marked destroyed and their refusal to surrender their lives could mean that a more destructive form of war returns to the planet.

Most of the time, the crew of the Enterprise comes across planets whose values aren’t quite up to date with those held by the enlightened Starfleet. Here, though, the crew is forced to deal with a planet that actually makes a pretty good point and achieved what seems to be far less destructive form of combat. Kirk makes an interesting argument, however, suggesting that the people of Eminiar VII have, in attempting to mute the destructive effects of war, helped mute the horror of it as well. By the time the credits roll on “A Taste of Armageddon,” you won’t be wrong if you’re not exactly thinking of Starfleet as the good guys this time.

7) Space Seed

“Space Seed” introduced Star Tre k’s most famous antagonist, Ricardo Montalban ’s genetically enhanced 20 th century superman Khan Noonien Singh. The Enterprise comes across a long-lost vessel, the Botany Bay, that contains Khan and 84 of his crew. Soon, Khan is using his enhanced cunning to take control of the Enterprise.

One of the reasons Khan works so well as a foil for Kirk is because he’s both physically and mentally superior to the Starfleet Captain, but also shares Kirk’s charisma. He’s an easy bad guy to root for and his backstory raises some interesting questions about what Earth’s Eugenics Wars were like in the 1990s.

While “Space Seed” is Khan’s sole appearance in the series, Montalban would famously reprise the role for Nicholas Meyer ’s Star Trek II: The Wrath of Khan in 1982. Benedict Cumberbatch would then play an alternate reality version of the character in Star Trek Into Darkness .

The Enterprise comes into territorial conflict with the Gorn, a race of reptilian creatures with whom Starfleet has never dealt. When conflict threatens to breaks out with the Gorn ship, both vessels are disabled an incredibly powerful race called the Metrons. To settle the issue, the Metrons will have Captain Kirk face off against the Gorn captain on a rocky desert planet. Even though the Gorn easily outmatches the Starfleet Captain physically, Kirk has a few tricks up his sleeve.

As with “A Taste of Armageddon,” “Arena” focuses on a transference of a larger conflict into a smaller one. While the former dealt a bit more with the ethics in doing so, “Arena” places more like a sporting event. On the bridge of the Enterprise, the crew is helpless to do anything but watch as Kirk and the Gorn captain battle to the death.

“Arena” has become one Star Trek’s most famous episodes primarily due to its incredible Gorn costume. While it has a degree of 60s sci-fi cheese, it still looks quite a bit better than attempts to later bring back the Gorn species with CGI on Star Trek: Enterprise .

5) The Trouble with Tribbles

One of Star Trek’s most famous episodes brings the Enterprise to Space Station K-7 where there is some fear that visiting Klingons might disrupt the delivery of much a needed grain to an Earth colony. Meanwhile, Nichelle Nichols ’ Uhura goes shopping and purchases a Tribble, a small purring creature that looks like a ball of hair. Unfortunately, it turns out that Tribbles are born pregnant and they begin to multiply exponentially.

“The Trouble with Tribbles” is a fairly light-hearted adventure that also feels like a day in the life for the crew of the Enterprise. Kirk’s attempts to deal with Federation politics wind up taking a back seat to the tribble problem as a memorable Star Trek species is born.

For the franchise’s 30 th anniversary, Star Trek: Deep Space Nine would return to “The Trouble with Tribbles” with an episode called “Trials and Tribble-ations”. In it, the crew travels back in time to prevent a plot to assassinate Captain Kirk during the events of “The Trouble with Tribbles,” digitally inserting actors into the background of the original episode with an adventure that makes use of impressive visual effects to tell a concurrent narrative.

4) Mirror, Mirror

Quite arguably the definitive pop culture example of parallel realities, “Mirror, Mirror” finds Kirk, McCoy, Scotty and Uhura in a transporter accident that swaps them with their counterparts from an alternate timeline. While the Enterprise is negotiating for dilithium on behalf of the United Federation of Planets in the regular timeline, the alternate history sees an aggressive Enterprise take the valuable resources by force in the name of the Terran Empire.

“Mirror, Mirror” is particularly famous for having a goateed Spock in the mirror universe. The “evil” goatee has become iconic in pop culture to represent all kinds of evil twins and alternate reality doppelgangers.

Although there were several novels and comic books that made use of the Mirror Universe, it would be nearly three decades before the timeline would return in the official Star Trek canon. The second season Star Trek: Deep Space Nine episode “Crossover” would make visits to the parallel timeline a nearly annual event for the spinoff series.

3) Balance of Terror

When the Enterprise encounters a Romulan vessel, the two ships come into combat and soon leave one another disabled and floating in space. Each races to make repairs before the other to claim victory in an encounter that reveals surprising new details about an old Starfleet foe.

In the Star Trek timeline, Earth experienced a brief but intense war with the Romulan Star Empire about a century earlier. Because the combat occurred in space, Earth never learned what Romulans look like. Here, it’s revealed that they’re a warlike offshoot of the Vulcan species, leading to some immediate tension between Spock and one of his crewmates.

A throwback to submarine thrillers like The Enemy Below and Run Silent, Run Deep , “Balance of Terror” is elevated by Mark Lenard’s pre-Sarek appearance as the commander of the Romulan vessel. As the viewpoint shifts from the Enterprise to the Romulan vessel, we find that he and Kirk are not so different in their adherence to their duty.

2) Amok Time

The first episode of Star Trek ’s second season reveals a Vulcan secret. Every seven years, the species goes through a mating cycle in which they must return to Vulcan and take a mate. Unfortunately, Spock’s would be mate demands the koon-ut-kal-if-fee, a battle to death between her suitor and a champion of her choosing. When she chooses Captain Kirk, both officers must fight in a Vulcan ceremony that will not end until one of them is dead.

Not only does “Amok Time” deliver on its promise of an epic Kirk vs. Spock fight to the death, but it’s a great example of Spock growing to trust and appreciate his crewmates. It’s an intensely personal story for Spock and it culminates with a fantastic line from the character.

“After a time,” Spock tells a Vulcan woman who has rejected him in favor of another suitor, “You may find that having is not so pleasing a thing after all as wanting. It is not logical, but it is often true.”

For that line alone, “Amok Time” deserves its honored place in Star Trek history.

1) The City on the Edge of Forever

It’s pretty much universally understood that the penultimate episode of Star Trek ’s first season is the franchise’s very finest story. Having accidentally injected himself with a drug that drives him crazy, DeForest Kelley ’s Dr. McCoy beams down to an alien planet where an ancient gateway, the Guardian of Forever, allows passage through time and space itself. A crazed McCoy travels back to Earth in the 1930s and does something that stops Starfleet from having ever existed. With no other choice, Kirk and Spock travel back themselves in the hopes of restoring the timeline.

It’s in the 1930s that Kirk and Spock meet Joan Collins ’ Edith Keeler a thoroughly lovely young woman who has dedicated herself to helping the less fortunate in a New York Mission. As they search for McCoy, Kirk begins to develop a relationship with Edith. And then the bad news hits: in order to fix the timeline, Edith Keeler must die.

The need for Edith Keeler to die is made all the more tragic by the fact that she’s not in any way a bad person. Spock explains that her success at organizing a pacifist movement in the United States will lead to the United States delaying its entrance into World War II. It is peace that she’s fighting for and in the name of peace that she must be sacrificed.

“The City on the Edge of Forever” is, simply, the epitome of what science fiction has to offer, bolstered by an original script by legendary author Harlan Ellison and a perfect romance between William Shatner and Joan Collins.

“Let me help,” smiles Kirk to Keeler as they a New York street together, he comments on her choice of words. “A hundred years or so from now, a famous novelist will write a classic using that theme. He'll recommend those three words, even over 'I love you’.”

For all the franchise’s many adventure across space and time, none come quite close to the simple, tragic elegance of “The City on the Edge of Forever”.

The 10 best Star Trek: The Original Series episodes, ranked

It’s hard to imagine today, but back in the late 1960s, the original Star Trek was not considered a hit. The ambitious science fiction series was constantly on the brink of cancellation and was cut short only three years into its planned five-season run.

10. Mirror, Mirror (season 2, episode 4)

9. a taste of armageddon (season 1, episode 24), 8. the menagerie, parts i and ii (season 1, episodes 12 and 13), 7. the doomsday machine (season 2, episode 6), 6. the corbomite maneuver (season 1, episode 11), 5. the devil in the dark (season 1, episode 26), 4. the trouble with tribbles (season 2, episode 15), 3. where no man has gone before (season 1, episode 4), 2. the city on the edge of forever (season 1, episode 29), 1. balance of terror (season 1, episode 15).

However, it’s important to put Trek ’s apparent failure into historical context as, given that most markets in the U.S. had only three television channels to choose from, even a low-rated show like Star Trek was being watched by about 20% of everyone watching television on a Thursday night, or roughly 10 million households. This year’s season of HBO’s Succession was viewed by roughly 8 million households a week , which makes it a hit by today’s standards. Star Trek ’s audience only grew once it went into reruns in the early 1970s, and by the time Star Trek: The Motion Picture hit theaters in 1979, it was a genuine cultural phenomenon. Today, the Star Trek franchise is considered one of the crown jewels of the Paramount library.

Though arguably outshined by its most prosperous spinoff, Star Trek: The Next Generation , Star Trek: The Original Series holds up remarkably well for a vision of our future imagined nearly 60 years in our past. It’s a space adventure series that tackles social or political issues from what was, at the time, a daring and progressive perspective informed by the contemporary civil rights movement, sexual revolution, and backlash against the Vietnam War. Conveying these values through fanciful science fiction didn’t only allow its writers to get away with a lot of subversive messages, it also delivered them in a way that remains fun to watch decades later — fun enough that fans are willing to forgive when its ideas, or its special effects, crumble under modern scrutiny.

These 10 episodes, however, unquestionably stand the test of time, and thanks to the continuity-light nature of mid-20th century television, any one of them could be your first Star Trek episode. (Be aware, however, that the order in which classic Trek episodes are listed varies depending on the source. For our purposes, we’re using the numbering from streaming service Paramount+ .)

Even if you’ve never seen an episode of Star Trek , you’re bound to be at least a little familiar with Mirror, Mirror through cultural osmosis. In this 1967 classic, Captain Kirk (William Shatner), Dr. McCoy (DeForest Kelley), Lt. Commander Scott (James Doohan), and Lt. Uhura (Nichelle Nichols) are accidentally transported to an alternate universe, where they encounter dastardly evil versions of their beloved shipmates. Instead of the benevolent United Federation of Planets, this ship serves the fascist Terran Empire, which threatens to annihilate a peaceful planet for refusing to submit to itsrule. Our heroes are forced to pose as their evil counterparts while they search for a way home and try to avert the genocide they’ve been ordered to perform.

This all sounds heavier than it is — like much of classic Trek , Mirror Mirror is very camp, with brightly colored costumes, over-the-top performances, and a general sense of fun. The cast is clearly having a ball playing the wicked versions of their characters (or playing the good versions of their characters playing the wicked versions), and it’s no wonder why multiple future incarnations of Trek would return to the Mirror Universe, usually for wacky adventure episodes. (For a more grim and brutal take on this same concept, visit the back half of Star Trek: Discovery ’s first season.) However, Mirror, Mirror still comes complete with Trek ’s famous humanist optimism, as Kirk tries to convince this universe’s menacing, bearded Spock (Leonard Nimoy) that regimes ruled by fear are unsustainable and, therefore, illogical. Given enough time, peace and cooperation will always win out over hate and violence.

A Taste of Armageddon may not appear on many “Best Of” lists, but it’s 100% pure, uncut Star Trek . In this episode, Kirk and company visit Eminiar VII, a seemingly peaceful planet that is, in fact, embroiled in a centuries-long war with a neighboring world. Rather than fire actual bombs at each other, the combatants conduct simulated attacks, determine the hypothetical death toll, and then order the “dead” citizens to report to disintegration chambers. When Kirk and his landing party are recorded as casualties, they decide to put an end to Eminiar VII’s supposedly “civilized” method of warfare.

While Kirk arguably has no right to interfere with how this sovereign planet conducts its affairs, the point of A Taste of Armageddon is to reflect on America’s attempt to make constant military conflict more palatable, or even invisible to the average American. Or, in a larger sense, it’s a commentary on the ease with which a culture can become accustomed to death and violence, so long as it’s part of an established routine. Because these simulated bombings leave homes, industry, and even the military infrastructure itself totally unharmed, it’s easy to forget that Eminiar VII is even at war — that is, until it claims your life or the life of someone you love.

When even these losses are framed as necessary sacrifices to maintain normalcy, it minimizes the incentive to make peace. Kirk (and, by extension, writers Robert Hamner and Gene L. Coon) argues that war is revolting no matter how much you dress it up, and that it must be brutal, terrifying, and omnipresent for all involved, or else it will never stop. The past half-century of perpetual U.S. military intervention abroad has proven this thesis to be chillingly accurate.

If you’re watching Star Trek on Paramount+, you’ll notice that the episode it has listed as “season 1, episode 1,” The Cage , isn’t exactly the show you were expecting. Instead of the famous Captain James T. Kirk, the USS Enterprise is under the command of Captain Christopher Pike (Jeffrey Hunter), and apart from Mr. Spock — who smiles?! — the rest of the crew is also unfamiliar. That’s because The Cage is Star Trek ’s original pilot episode, which was rejected by NBC, leading to a second pilot being commissioned with a new cast and modified tone. The Cage wouldn’t air as its own episode until 1988, but during production of Star Trek ’s first season in 1966, a budget crunch led to writer/creator Gene Roddenberry repurposing footage from the already-completed pilot into a new script in the form of flashbacks.

This fiscally minded decision endowed Star Trek and its characters with a history, instantly making the universe a bigger and more interesting place. The two-part Menagerie sees Spock, the only remaining character from the original cast, commandeer the Enterprise for the sake of its previous captain, Christopher Pike. On the way to a forbidden planet, Spock uses mysterious footage from an adventure 13 years in the past to explain his rash actions.

If you’ve already watched The Cage , then The Menagerie will seem like a glorified clip show, in which Kirk and company spend half the runtime watching a previous episode. However, before the streaming era, The Cage was usually the last episode of The Original Series that a fan would see, rather than the first. In recent years, however, The Cage and The Menagerie have taken on a new role, as bookends to the adventures of Christopher Pike, as portrayed by Anson Mount on modern spinoff Star Trek: Strange New Worlds . Strange New Worlds (as well as the second season of Star Trek: Discovery ) take place after The Cage , but before The Menagerie , allowing us to get to know Kirk’s predecessor in his own context, as well as developing the bond between Pike and Spock that will eventually drive the Vulcan to mutiny. Even without any of this context, however, The Menagerie is an exciting two-hour event, an eras-spanning mystery that will make you wonder why NBC passed on the Star Trek pilot in the first place.

Due to the production constraints of 1960s television, the original Star Trek didn’t often aim for large-scale, awe-inspiring space action. The Doomsday Machine is the closest that classic Trek ever came to “epic,” and as compelling a story as it is, it’s also Exhibit A as to why such a thing was impractical with the resources available. Though its original effects required no small amount of ingenuity (they couldn’t afford to give their Enterprise model battle damage, so they bought one off the rack from a toy store and distressed it), the results look mighty corny on a modern high-definition television.

Still, the episode gained fame as boasting the largest-scale action of the series, as the Enterprise teams up with her badly damaged sister ship, the USS Constellation, to take on a huge planet-eating weapon. It also presages a theme that would become common in Star Trek feature films , as the Constellation’s grief-stricken Commodore Matt Decker (guest star William Windom) embarks on a foolhardy quest for revenge against the monster that bested him. (Trek would revisit Herman Melville’s Moby-Dick in Star Trek II: The Wrath of Khan and Star Trek: First Contact .)

The episode still works in a cheesy B-movie sort of way, which some fans would argue is the way it should still be enjoyed. However, when the series was remastered for high definition in the mid-2000s, the decision was made to recreate most of the special effects shots for the series using modern technology, since the originals were never expected to hold up to modern standards. Most of these recreations are very faithful, to the extent that uninitiated viewers might not even realize they’d been replaced. In the case of The Doomsday Machine , however, the producers and effects artists returned to the episode’s original script and attempted to realize writer Norman Spinrad’s initial vision for the space battle sequences. The team at CBS Digital doesn’t sacrifice the overall aesthetic of the series, but they do give us a peek at what The Doomsday Machine — and by extension, the entire Original Series — might have looked like with a feature film budget.  

There may be no better introduction to the character of James T. Kirk than The Corbomite Maneuver . The first episode produced after the series was picked up (though it didn’t air until later in the season), The Corbomite Maneuver finds the Enterprise at the mercy of a massive alien vessel and accused of trespassing in its territory. Unable to outrun or outgun his mysterious adversary, Kirk does what he will later become famous for doing — he cheats. Or, rather, he changes the conditions of the contest from one of technological superiority to one of cunning and guile. In the process, we get to learn a bit about how each of the main characters handles the intense stress of a seemingly hopeless scenario, contrasted against the more relatable Everyman Lt. Bailey (guest star Anthony Call). Though the action rarely leaves the bridge of the Enterprise, it is, in its own way, one of the most thrilling episodes of the series.

Moreover, The Corbomite Maneuver sets the tone for Star Trek as a series. It’s an hour of adventure that is punctuated by moments of thoughtful introspection, warm friendship, and corny jokes. Its depiction of Starfleet and the Enterprise are clearly inspired by military tradition, but the message of the episode is one of compassion and patience rather than conquest. These are scientists, not soldiers, and while they experience fear and doubt, none of their human frailties are a match for their curiosity. If this is what the future of humanity looks like, we want to be a part of it.

When Star Trek is running on full thrusters, it is equal parts silly and profound. In The Devil in the Dark , the Enterprise is sent to the aid of a mining colony where workers are being hunted and killed by an unstoppable monster made of rock. We know that the monster is made of rock because the characters say so; It looks a lot more like it’s made of spray-painted Styrofoam and a shag rug. But as the tension rises and the mystery deepens, the goofiness of the rock monster becomes irrelevant, or even a boon to the story.

Though it begins as a hunt for a merciless alien creature, The Devil in the Dark becomes a story about prejudice and the universality of what we (in our limited earthly experience) would call “basic human rights.” This message is conveyed through cheesy 1960s TV production values and some very hammy acting, but the results are pure and unpretentious, the sort of storytelling that is equally impactful on a jaded adult and a wide-eyed child.

Here in the post-post-postmodern 2020s, we’re all total pros at deconstructing genre tropes. The practice of subverting the audience’s expectations as to what kind of story they’re watching or who the good guys and bad guys are wasn’t new in 1967, either, but in the sci-fi film and television of the era, the big scary monster is usually just a big scary monster. The Devil in the Dark  exemplifies one of Star Trek ’s most enduring themes: that the unknown might seem terrifying, but if you take the time to understand it, it’s actually beautiful.

Star Trek is always science fiction, but its format offers a lot of flexibility in terms of how to interpret that genre. Even within the course of a single series or season, most Star Trek shows alternate between a variety of tones and secondary genres, from grim political drama to steamy romance, or in the case of this episode, kooky workplace comedy. The Trouble with Tribbles pits Captain Kirk and his gallant crew against their most stubborn foe yet — bureaucratic red tape. Assigned to look after a container of grain that Federation administrators insist is gravely important, the Enterprise becomes entangled in a very silly misadventure involving an invasive species of adorable, self-replicating furballs. For a captain accustomed to dealing with high-stakes diplomacy and galactic defense, this is his worst workweek ever.

As lousy a time as Kirk is having, The Trouble with Tribbles is tremendous fun. It is neither the first, nor the last broadly comedic episode of Star Trek , but it is the gold standard by which all Trek comedies are measured. Like any good Trek, it has stakes, a fun science fiction premise, and charming moments of character, but everything is set just a little bit askew, and the characters have noticed. It isn’t parody, it’s situation comedy, only a situation that you’re unlikely to find yourself in unless you’re the crew of a Federation starship. Almost every subsequent Trek series would chase that Trouble with Tribbles heat at least once ( Star Trek: Lower Decks  is basically The Trouble with Tribbles: The Series ), with varying levels of success, but the original remains an untouchable classic.

After The Cage was rejected by NBC, Desilu Studios (under the leadership of comedy queen Lucille Ball herself) took a second swing at the series, with a new cast and a faster paced action-adventure story. This second pilot, Where No Man Has Gone Before , introduces William Shatner as Captain James T. Kirk, as well as George Takei as Lt. Sulu, James Doohan as Scotty, and Leonard Nimoy’s new, more stoic interpretation of science officer Spock.

The episode sees Kirk’s friend and mentee, helmsman Gary Mitchell (guest star Gary Lockwood), bombarded with cosmic radiation that grants him increasingly godlike powers. As Gary grows more dangerous and cruel, Kirk must weigh his love for his friend against his duty to his crew. The scenario immediately establishes the dynamic between Kirk and Spock (compassionate leader versus his coldly practical advisor), though Spock’s regular debate partner, the emotionally driven Dr. McCoy (DeForest Kelley), would not appear until Trek was ordered to series.

Where No Man Has Gone Before  is a little less fun and colorful than the episodes that followed, with a tone more closely resembling heady 1950s sci-fi films like Forbidden Planet or The Day the Earth Stood Still . In a way, it’s the classic Trek episode that feels the most like Star Trek: The Next Generation ; It’s talky, deliberately paced, just a little bit sterile. In Where No Man Has Gone Before , the galaxy is not only wondrous, but also eerie and unsettling. Had this been the tone the series stuck with, it might not have become a global sensation, but as a single episode, it stands out as one of the very best.

To some Trekkies, ranking The City on the Edge of Forever anywhere but at No. 1 is unthinkable. This time travel tale – written by sci-fi author Harlan Ellison and then heavily revised by Trek story editor D.C. Fontana — won Star Trek its first Hugo Award, and is widely considered to be the finest hour in the history of the series, if not the franchise as a whole. The episode’s legendary status is well-deserved, but we don’t quite have the heart to declare it the ultimate Star Trek episode, on account of how little of it takes place in the 23rd century or aboard the Starship Enterprise. The City on the Edge of Forever  is an outlier, and as such, naturally stands apart from the pack, giving it an edge in any conversation about Star Trek . Its placement here at No. 2 is sort of a counter to that advantage.

Make no mistake, however — despite mostly being set in New York in the year 1930, City on the Edge is Star Trek to its core. Sent back in time to correct an accidental alteration of Earth’s history, Kirk and Spock take up residence in a homeless shelter run by idealistic philanthropist Edith Keeler (guest star Joan Collins). Keeler turns out to be the key historical figure whose destiny must be fulfilled, but there’s a problem — Kirk has fallen in love with her. This romance complicates the mission, as Kirk and Spock are confronted with a grave moral dilemma with their entire reality hanging in the balance. Keeler is a visionary who believes in the beautiful future that Kirk calls home. But, in order for that future to exist, must something terrible be allowed to happen in her present? It’s an emotionally gripping tale that, if it had been told on a modern television show, would have changed its characters forever.

Star Trek is built on a central contradiction. It’s an adventure series about officers in a fleet that we are told, unconvincingly, is not a military organization, aboard a vessel that carries enough firepower to demolish a continent. It’s a show about peace in which things have a habit of blowing up. To reconcile this cognitive dissonance, one need only look to this key episode of The Original Series , Balance of Terror . In this early chapter, the Enterprise witnesses an Earth base being destroyed by an old enemy, the Romulan Empire. The Romulan ship has the ability to become invisible both to scanners and the naked eye, and attempts to escape to its own side of the neutral zone between their two territories before it can be apprehended.

The Enterprise is ordered to capture or destroy the Romulans before they make it home. Whether or not they succeed, there may be war. Kirk has his orders, and as we soon discover, so does the Romulan commander (guest star Mark Lenard), who is no happier about this turn of events than Kirk is. Throughout the episode, we cut back and forth between the action on the Enterprise and aboard the Romulan vessel, as two keen military strategists attempt to outmaneuver each other and stay alive, both locked in a struggle they’d rather had never begun.

Balance of Terror is a sci-fi twist on a submarine battle, but more than that, it’s a commentary on war, the rivalries between nations, and the wounds and prejudices they create. The Enterprise isn’t loaded with photon torpedoes because Starfleet is itching for a fight — it’s armed because sometimes it has to be, and when Kirk and his crew ride into battle, there’s nothing glorious about it. On the other side of any conflict is a person or people who have their own mission, their own values, and perhaps even their own reservations about fighting. It is not possible to avoid every fight, to preempt every war with diplomacy. But when blood is shed, there is no victory and there are no winners. There is tragedy, and there are survivors. And, finally, there’s the hope that the next time these two nations clash, they’ll be a little more willing to talk to one another.

It's been a long hiatus for Doctor Who fans, but the series is back with a new 60th anniversary special called Doctor Who: The Star Beast. This is the first of three specials that will feature the Tenth Doctor performer David Tennant appearing as a new Fourteenth Doctor. Tennant's Doctor is also joined by Catherine Tate's Donna Noble, his former companion from the fourth season.

The Doctor has had numerous companions for his time travel adventures over the last six decades. But when compiling this list of the seven best Doctor Who companions, we decided to stick with the companions from the modern revival series that started in 2005. There is only one exception to that rule, and that's because the character in question had the unique chance to play a major role in both classic Doctor Who and in the modern era. But if you want to know who landed the top spot, you'll have to keep on reading. 7. Captain Jack Harkness

In the Futurama episode Where No Fan Has Gone Before, the wisecracking robot Bender describes Star Trek as having “79 episodes — about 30 good ones.” And, if we're being honest, Bender's not wrong. Across the franchise, there are now roughly 900 canonical installments, and out of a field that large, there are naturally dozens, even hundreds of entries that you can simply disregard. Of course, like any fanbase, Trekkies contain multitudes, and we don’t all agree on which episodes deserve the scrap heap. One fan’s space junk is another fan’s latinum, and there’s no accounting for taste. We’ve selected ten episodes from across the history of the franchise that some fans might tell you to skip, but that we think deserve your attention. Is one of your dark horse faves on our list?

10. The Time Trap (TAS season 1, episode 12)

This year marks the 30th anniversary of The X-Files, one of the most popular genre shows in the history of network TV. Over the course of nine seasons, from 1993 to 2002, series creator Chris Carter and his team of writers took viewers inside some of the strangest and the most horrifying cases of the paranormal that they could imagine. Anything from aliens to demons and monsters was in play, while the show developed its own mythology and an overarching story.

In honor of the show's 30th anniversary, we're looking back at the 10 best episodes of The X-Files and ranking them from worst to best. Unlike some of the previous best-of lists for this show, we're not focusing only on the standalone episodes or the monsters-of-the-week installments. It's become fashionable to bash the show's mythology episodes because Carter and Company couldn't bring the story to a satisfying resolution. But those episodes were a large part of the reason why this show was so fantastic in its prime, and it would be a disservice to the series itself if we didn't give those stories their due. 10. Requiem (Season 7, Episode 22)

TOME OF NERD

Star Trek DS9: The Complete Dominion War Guide

I love Star Trek:  Deep Space Nine . Not only does it have some of the best characters in Star Trek canon, but DS9 also pushed the boundaries of syndicated storytelling by introducing serialized plotlines. While every show and their mother is serialized today, procedurals were the norm in the 90s, especially with Star Trek . DS9 dared to tell a deeper and more complex story. That story is known as the Dominion War.

While Deep Space Nine  has some amazing non-Dominion-centric episodes, you can’t really watch the show without feeling the Dominion’s presence. The Dominion War is the core story underlying the entire series, so it deservedly caters a lot of attention. But for a show that is 132 hours long, it can be a bit intimidating to dive in, especially if you only want to follow the Dominion War arc.

Thus, I took it upon myself to create a complete Dominion War viewing guide. But as I attempted to identify the essential episodes of the series, I discovered I was pulling at a thread. If episode X was important, then you had to have seen episode Y, which of course means you need episode Z. In the end, I had not one, but three viewing lists. So here they are, with many more details below:

Your first question is probably along the lines of: Why are there three lists? How big a nerd are you? To the later question I would say: very. But I will expand further on the first question.

Ultimately, one list wouldn’t work for everyone. Some people want a streamlined viewing of the Dominion War while others would appreciate a more fleshed out version of the story. Obviously, determining the importance of each episode is not an exact science. But as I rewatched each episode, I discovered that most episodes fall into one of three categories:

Essential : A pivotal episode that is integral to understanding the Dominion War story. A can’t miss.

Expanded : Expands on the overarching story, focusing heavily on the Dominion. Episodes sometimes includes lasting consequences, but not required viewing.

Supplementary : Stories tangential to the overarching story, but the Dominion still play a noteworthy role in the episode.

For the sake of brevity, I have not included every single episode that mentions the Dominion, because that would become superfluous. I am including any episode in which the Dominion or their effects are featured prominently. Using the criteria above, we end up with three viewing lists:

The Essential List will provide the most streamlined viewing by including only the most important episodes of the series. You will miss out on a lot, but you will still get to watch some of the best episodes of the series while watching the complete Dominion War arc.

The Essential + Expanded List will further flesh out the greater Dominion War themes. Not only do you get all the of integral story, but you will also get most of the backstory. This provides a deeper understanding of the characters (on both sides) and hopefully a greater appreciation of the Dominion War arc.

The Essential + Expanded + Supplementary List is the closest version to a complete list possible. In addition to the above, it includes some fairly inconsequential episodes regarding the Dominion and/or tangential events to the war that help shape the story. For those seeking a “complete” list without watching the whole series, this is it.

Below you will find a summary and justification for each episode in the guide. Because the list encompasses nearly the entire series, there will undoubtedly be spoilers. Read at your own risk.

Dominon War Episode Summaries and Justifications

2×07 rules of acquisition and 2×10 sanctuary (supplementary).

Rules of Acquisition and Sanctuary contain the first two whispers of the Dominion. The malevolent force is only hinted at, but it’s clear that they are a major player in the Gamma Quadrant. It’s fitting that the first introduction to the Dominion is through the eyes of the Ferengi. Their lust for profit and expansion immediately puts them in touch with the who’s who in the Gamma Quadrant. Sanctuary  doubles down on this premise, illustrating the power the Dominion wield by turning a race of people into refugees.

That being said, neither episode is particularly strong. Both suffer from Star Trek early-season-itis and the Dominion only play background roles within the episodes. Watch them if you want to see the foreshadowing, but they are the definition of supplementary material.

2×26 The Jem’Hadar (Essential)

The second season finale finally introduces the true might of the Dominion. The Jem’Hadar starts innocently enough with a Sisko family trip (plus Quark and Nog) into the Gamma Quadrant. But before long they come across a mysterious alien being hunted by the Jem’Hadar. As the episode slowly unravels, the true threat of the Dominion is revealed.

What’s great about this episode is that it shows just how outmatched the Federation and the Alpha Quadrant really are. The Dominion isn’t just a brute force enemy, but also incredibly intelligent and cunning. The Jem’Hadar already know plenty about the on-goings of the other side of the wormhole. And when push comes to shove, it is the Dominion that stands tall. An ominous introduction of the threat to come.

3×01/3×02 The Search Part 1 and 2 (Essential)

After the events of The Jem’Hadar , Sisko gets proactive in regard to the Dominion threat. The crew of DS9 head into the Gamma Quadrant in search of the Founders on board their brand new warship: the Defiant. The mission sends them head first into the Dominion.

The Search  again illustrates the superiority the Dominion has over the Federation. There is a continuing trend of not just being outmatched physically, but also strategically. This episode has a lot of twists and turns, with the final reveal setting the stage for the series moving forward.

3×06 The Abandoned (Supplementary)

Quarks purchases wreckage from the Gamma Quadrant that includes a baby Jem’Hadar (whoops). As the child rapidly ages, Odo, Sisko, and the others must decide the Jem’Hadar’s ultimate fate. Will he be given to the Federation for study or will the Jem’Hadar be allowed something more?

While The Abandoned touches on some key Jem’Hadar backstory, such as their addiction to Ketracel-white, the episode is fairly removed from the overarching story. The dynamic between Odo and the Jem’Hadar is interesting to watch unfold, but the episode is not the strongest. There is also a bizarre B story about 16-year-old Jake dating a 20-year-old Bajoran Dabo girl. Watch if you are interested in Jem’Hadar lore, but skippable otherwise.

3×17 Visionary (Supplementary)

Chief O’Brien is exposed to radiation poisoning, sending him back and forward through time. 5 hours in the future, O’Brien observes the events of a Romulan delegation’s briefing on the Dominion. O’Brien must unravel the mysteries of his time jumps while also trying to stay alive.

Visionary is very supplemental to the Dominion War, so much so that I almost didn’t include it in this list. Ultimately, I decided to include it because the episode foreshadows the Romulan’s stake in the Dominion and how severely they view the situation. The episode itself is also strong in its own right, with classic Star Trek time travel antics and mysteries. If you’re a fan of that stuff, watch Visionary . If you are only interested in the Dominion War, skip it.

3×20 Improbable Cause and 3×21 The Die is Cast (Essential)

After Garak’s shop is destroyed in an explosion, Odo discovers there is more to the story than a simple assassination attempt. Odo and Garak unravel a mystery that leads them all the way to the Tal Shiar and Obsidian Order. They discover the unlikely alliance of intelligence agencies is determined to preemptively strike the Dominion.

This is an excellent two-parter and could have easily been the season finale. Garak and Odo are two of the strongest characters in the show and until now haven’t interacted much. They display their entire range, bringing strong character moments to a story that is galactic in scope. Probably the best episodes yet on the list.

3×26 The Adversary (Essential)

Sisko and the crew of the Defiant are called to intervene in a possible coup on Tzenkethi. Things quickly turn south as their ship is sabotaged by a changeling. Sisko and the others must find a way to regain control of the Defiant before they unintentionally start a war with the Tzenkethi.

If it wasn’t for the ending, this episode would be supplementary. As a season finale, it is a fairly weak entry. It is by no means a terrible episode and it has big consequences moving forward, but the stakes never feel high. The episode falls into various tropes (self-destruct sequence cancelled at the last minute anyone?) and leaves us waiting for the inevitable resolution to the problem. You could also nit-pick the convoluted way in which the changeling attempted to start a Federation war with the Tzenkethi. But most of these criticisms aren’t deal-breakers. It is a middling episode, but required viewing.

4×01/4×02 The Way of the Warrior Part 1 and 2 (Expanded)

The Klingons decide to go on the offensive against the Dominion. They believe the recent coup on Cardassia was part of a Dominion plan to establish a foothold in the Alpha quadrant. In an effort to better understand the Klingon actions, Sisko recruits Worf. The crew of DS9 must find a way to stop the Klingons without starting a war.

A lot of guides say that this episode is essential viewing and I can see why. First, it establishes Worf as a main player on the show. Secondly, it introduces the Klingons being at war with basically everyone. But the Dominion never show themselves in this episode. The episode is more about the confrontation with the Klingons and the Dominion’s rippling effects on the Alpha Quadrant. It’s a fun 90 minutes of television and definitely worth a watch, but non-essential to the greater Dominion War arc.

4×04 Hippocratic Oath (Expanded)

Bashir and O’Brien become stranded on a planet and are captured by a group of Jem’Hadar. Their leader, Goran’Agar, reveals that his Jem’Hadar are attempting to free themselves from the addictive drug ketracel-white. Bashir and O’Brien must decide to help the Jem’Hadar or help themselves escape.

This episode contains a lot of backstory about the Jem’Hadar and the function they play within the Dominion. Specifically, how they view the Vorta as slave masters and the Founders as gods. It’s also a classic Bashir/O’Brien episode where we see their friendship and their conflict. There is a B story involving Worf learning to fit into his role on the station that is arguably stronger than the Bashir/O’Brien plot line. Watch if you are a Jem’Hadar completionist, otherwise you can pass.

4×07 Starship Down (Supplementary)

While negotiating a trade deal with the Karemma in the Gamma Quadrant, the Dominion attack. The Defiant is heavily damaged and must locate the Karemma ship within a gas planet, all while taking on two Jem’Hadar warships.

This episode is essentially the The Next Generation Season 5 episode Disaster . Members of the Defiant crew are separated and forced to bond through crisis. There are some noteworthy moments, such as Kira’s relationship with Sisko and his role as the emissary, but in general the episode is fairly rote.

4×11 Homefront and 4×12 Paradise Lost (Essential)

After a changeling bomb in San Francisco kills dozens of people, Sisko and Odo are recalled to Earth. Sisko is given the title of acting Chief of Starfleet Security as they investigate how to best stop the changeling threat. But when the clues don’t add up, Sisko and Odo believe something else is amiss.

This 2-part episode is classic DS9 fare in the best way possible. The episode looks at the lengths people go to protect themselves from an existential threat. How do we live our lives when anyone could be an enemy? Many of the themes ring truer today perhaps than when the episode initially aired. Light on action and heavy on ideals and philosophy. An excellent set of episodes.

4×23 To the Death (Expanded)

A group of Jem’Hadar strike Deep Space Nine. The Defiant crew hunt down the perpetrators, only to discover the Jem’Hadar are in possession of an Iconian Gateway. Now they must join forces with the Dominion to stop the rogue Jem’Hadar.

I had a hard time deciding how important  To the Death is to the Dominion War arc. It introduces Weyoun into canon and articulately displays the contempt the Jem’Hadar and Vorta have for one another. It’s also the first episode that shows the Dominion has flaws. But on the other hand, the plot itself is fairly inconsequential to the greater story. More of a one-off tale staring the Dominion. But it’s a good episode with a TNG callback to the Iconians. Definitely worth watching, but not essential.

4×26 Broken Link (Essential)

Odo becomes dangerously ill. With no other solution in place, the crew of the Defiant must head to the Gamma Quadrant to find the only people that can help Odo: the Founders.

While Broken Link is very much an Odo episode, the B story surrounding Garak really stands out. One of my favorite scenes is when Garak confronts the female Founder, asking if there were any Cardassian survivors from the events of The Die is Cast . Her response is chilling and dooming to the Cardassian people. The episode as a whole is strong and the conclusion resonates moving forward.

5×01 Apocalypse Rising (Essential)

While in the Great Link, Odo saw that Gowron is a changeling. Now Sisko, O’Brien, Odo, and Worf are tasked with going undercover and exposing Gowron.

This is a fun episode that I’m glad wasn’t stretched into a two-parter. For as exciting as the Klingon-version of the DS9 crew should be, it almost overstays its welcome. Most of the episode is simply standing around and observing Klingon culture, but even so there are good bits of humor and action. As always, the mission isn’t as straight forward as it seems. The ending also has lasting ramifications for the series.

5×02 The Ship (Supplementary)

The crew of the Defiant is on a planetary survey in the Gamma Quadrant when a Dominion Warship crashes. The wreckage would be of great importance to the Federation, but the Dominion arrive before it can be salvaged.

The Ship is a fairly tense episode, most of it being a standoff between the DS9 crew and the Dominion. It suffers from a few Star Trek cliches, such as the new characters that are just around to die. The episode also has a very Star Trek-y moral at the end, which it may or may not have earned. Certainly worth a watch, but it is non-essential to the overall story.

5×10 Rapture (Expanded)

After a holosuite accident (shocking!), Sisko begins to have prophetic visions. As Bajor is accepted into the Federation, Sisko starts to understand its greater purpose within the universe. Also, as you might have guessed, the visions are killing Sisko…

Rapture is the definition of an Expanded episode, but it is well worth watching. There is lots to love with plenty of foreshadowing. For as “big” as an episode this is, it is still intimate, focusing on Sisko, Kasidy, and Jake. Is the life of one man more important than understanding the future? Classic Star Trek .

5×14 In Purgatory’s Shadow and 5×15 By Inferno’s Light (Essential)

DS9 receives a Cardassian signal from the Gamma Quadrant. When Garak determines the message is from Enabran Tain, Worf joins him to investigate the origins of the signal. Back on the station, Dukat is hanging around and rustling feathers. Antics ensue on both fronts.

This two-parter is probably my favorite thus far in the series. This has everything you would want in a Dominion War episode. The highlight is Worf taking on Jem’Hadar after Jem’Hadar in battle. Also, the “reveal” near the end of the first episode is perfectly done. The episode has ramifications for the rest of the series. A fantastic and essential viewing.

5×21 Soldiers of the Empire (Supplementary)

Martok receives orders to investigate the disappearance of a Klingon warship in Cardassian space. Worf and Jadzia join under Martok’s command, but soon realize that low morale is putting the mission in jeopardy.

This is a mediocre episode with only the slightest relation to the overall story. You get a deeper glimpse of Klingon culture, but it isn’t anything a seasoned fan hasn’t seen before. If you are interested in watching “How Martok Got His Groove Back”, then go for it. Otherwise move on to the next episode.

5×23 Blaze of Glory (Supplementary)

When Sisko learns of a Maquis plan to attack Cardassia, he must turn to Michael Eddington for help. The unlikely duo enter the Badlands in search of the remaining Maquis. But can Sisko avoid the Dominion and stop an all-out war?

The episode only has a tangential tie to the Dominion War and is really more of a wrap up to the entire Eddington/Maquis-arc of the series. It’s a fine episode and you can’t help but enjoy the lovably-hateable Eddington. If you skip it, you won’t miss anything related to the Dominion arc.

5×25 In the Cards (Expanded)

The crew of Deep Space Nine has the blues. The Dominion threat grows and tensions are at an all-time high. In an effort to cheer up his dad, Jake attempts to acquire a Willie Mays rookie baseball card. Antics ensue.

With a summary like that, you’d be surprised how relevant this episode is. It’s one of the first episodes that illustrates the Dominion’s effect on everyday life on the station. In what should have been the main plotline of the episode, Weyoun is on DS9 negotiating a non-aggression pact with Kai Winn and Bajor. While the focus is on Jake and Nog’s comical adventure, the underlying themes are relevant to the series as a whole.

5×26 Call to Arms (Essential)

Sisko is determined to prevent more Dominion ships from entering the Alpha Quadrant. As more and more Alpha Quadrant powers sign non-aggression pacts with The Dominion, Sisko and the crew of DS9 decide to mine the entrance to the wormhole.

Call to Arms defines the future of the series and the Dominion War to come. In just one episode, the show manages to touch on nearly every notable plot-point in the series thus far. It’s a fantastic episode and the first true Dominion War episode. A must watch.

The Terok Nor Arc (Essential) – 6×01 A Time To Stand, 6×02 Rocks and Shoals, 6×03 Sons and Daughters, 6×04 Behind the Lines, 6×05 Favor the Bold, 6×06 Sacrifice of Angels

Shit just got real.

The six episode arc that kicks off season 6 is quintessential Deep Space Nine. It is the first real attempt at serialization and multiple narratives. Nearly every major character has a storyline running throughout these episodes (except poor Bashir).

The arc as a whole is an amazing character piece. On the station, Dominion and Cardassian antagonists are given ample screen time next to our usual DS9 heroes. Odo’s character arc is particularly noteworthy. Worf has joined Martok’s crew for his own adventures. Oddly enough, the Starfleet characters (Sisko, Jadzia, Bashir, O’Brien) are probably the least interesting, albeit no less essential.

What else can be said? This is the best 6-episode run of the series yet. Unskippable for the Dominion War arc.

6×09 Statistical Probabilities (Expanded)

Dr. Bashir is temporarily in care of an eccentric group of genetically enhanced individuals. After witnessing their cognitive abilities, Bashir believes they can assist with the ongoing Federation/Dominion negotiations.

This episode is borderline “Supplementary” because the focus is on Bashir’s relationship with the genetically enhanced quartet. But Statistical Probabilities establishes some important story elements, even if somewhat in the background. Most notably, Damar’s ascension into Dukat’s previous role as leader of Cardassia is worth noting. It’s a middling, non-essential episode, but worth a watch at least once.

6×10 The Magnificent Ferengi (Supplementary)

When Quark learns of his mother Ishka’s capture by the Dominion, he puts together a ragtag group of Ferengi to rescue her. With the vorta Keevan in tow, Quark and his team go to Empok Nor for a prisoner exchange. Antics ensue.

The episode is a classic “Ferengi” episode, but that isn’t a bad thing. It’s actually quite comical at times and the Dominion characters are of the love-to-hate variety. I was glad to see Keevan return and Yelgrun (Iggy Pop!) is a great vorta as well. The reason this episode is classified as Supplementary is because when all is said and done, it is of no consequence to the greater Dominion War arc. There is a one-off line from Yelgren about the Breen, which could be construed as foreshadowing, but that’s about it. Still a fun episode and worth a watch, especially if you are a Ferengi fan.

6×11 Waltz (Expanded)

Sisko boards the U.S.S. Honshu to escort Dukat to trial. But after a Cardassian ambush, the Honshu is destroyed, leaving Sisko and Dukat stranded on a dangerous planet. Worf and the Defiant crew must rescue Sisko before he succumbs to the violence of an unhinged Dukat.

Waltz is a fine episode that delves into the inner workings of Dukat’s mind, but I went back and forth on how integral it is to the Dominion War arc. On the one hand, Dukat is obviously a central figure to the show and this episode is ultimately the first step towards the final Dukat and Sisko confrontation. But on the other hand, Dukat’s character is reinvented a couple times between here and there, making this episode less mandatory viewing. At the end of the day, this is a skippable episode in terms of plot, but worthy of a watch.

6×14 One Little Ship (Supplementary)

O’Brien, Dax, Bashir shrink in size to investigate an anomaly. During their mission, the Defiant is attacked and commandeered by Jem’Hadar. Now the Defiant’s only hope rests in one little ship.

Look, it’s Honey I Shrunk the Kids meets Deep Space Nine . Depending who you are, that’s either a good thing or a bad thing. The episode is downright goofy. In terms of the greater Dominion War, there is an underlying Alpha versus Gamma Jem’Hadar plotline, but that is never mentioned again. If you are a completionist looking for a ridiculous episode, this one is for you. Otherwise, it’s an inconsequential episode.

6×19 In the Pale Moonlight (Essential)

Sisko recounts his plan to bring the Romulans into the Dominion War.

Watch this episode. It’s considered to be one of the series’ bests. While the story is galactic in size, the episode is truly about Sisko and how far he will go to save the Alpha Quadrant from the Dominion. I could write a whole article on this episode, so I say again, just go watch it.

6×22 Valiant (Expanded)

When Jake and Nog’s runabout is ambushed by a Jem’Hadar force, they are rescued by Red Squad, a group of elite Starfleet cadets. When Nog is quickly promoted to Chief Engineer, Jake questions the morality of what is occurring.

Valiant isn’t essential viewing for the Dominion War story, but it does wrap up the Red Squad storyline from wayyyy back in Homefront / Paradise Lost . It also introduces the new Jem’Hadar battleship. It’s borderline Supplementary, but ultimately I decided it was worth the Expanded designation. Worth a watch for fans of Jake and Nog or those who want a fuller view of the Dominion War.

6×26 Tears of the Prophets (Essential)

Sisko leads the Alpha Quadrant alliance into Cardassian space, despite visions from the Prophets warning him otherwise. Dukat returns to Cardassia, promising to sway the war in favor of the Dominion.

Oh boy. This is undeniably the most pivotal episode of the show thus far. The season six finale touches on almost every major character on both sides of the war. And of course, Tears of the Prophets is most remembered as being one of the most tragic of the series. This is a can’t miss episode. Bring your tissues.

7×01 Image in the Sand and 7×02 Shadows and Symbols (Essential)

With the wormhole closed, Sisko returns to Earth in an attempt to reconnect with the Prophets. On DS9, the crew deals with the ramifications of Sisko absence. Months later, Sisko has a mysterious vision from the Prophets and is joined by a familiar guest.

This two-part episode sets the stage for the rest of the series. There are some big revelations and the introduction of a sometimes controversial character (Ezri). With the time jump, the episodes do a good job at catching up with all of DS9 regulars, friend and foe. Obviously an important episode in the greater Dominion War arc.

7×06 Treachery, Faith, and the Great River (Essential)

Odo receives a secret message from an old contact on Cardassia. When he arrives, he discovers Weyoun wishing to defect to the Federation. Back on the station, Nog helps O’Brien procure a graviton stabilizer through Ferengi ingenuity.

This episode plays a surprisingly important role in the series despite its fairly innocuous plotlines. Sure, Weyoun defecting to the Federation sounds big and important, but the significance is in the foreshadowing information revealed. I initially thought about marking this episode as Expanded, but ultimately I felt viewers would be lost without it.

7×07 Once More Unto the Breach (Supplementary)

Kor, the Dahar master, seeks help from his friend Worf to find an honorable death in the Dominion War. Martok, on the other hand, doesn’t particularly care for Kor, the Dahar master. After Worf appoints Kor, the Dahar master, to an officer position on the Ch’Tang, we soon discover why.

While the Dominion War plays a central role in this episode, it is truly about wrapping up the story of Kor, the Dahar master. Can the old and weathered veteran find a place of value in the Klingon Empire and earn an honorable death? If you are a fan of Kor, the Dahar master, than this is a must watch. For those looking for only the integral episodes of the series, feel free to pass on this one. But before you go, did I mention that Kor is the Dahar master?

7×08 The Siege of AR-558 (Expanded)

Sisko and the crew of the Defiant stop at AR-558 for a supply drop. But when the Defiant is attacked by Jem’Hadar fighters, Sisko and crew decide to stay on the planet to assist the units on the frontline.

This is one of the few episodes that deals directly with the horrors of the Dominion War. Most of the series takes place in space (obviously) so it’s quite interesting to get a view of the war from the perspective of the foot-soldiers. While the episode doesn’t deal with the greater war effort, at least one character will deal with ramifications from the episode down the road.

The Final Chapter – 7×17 Penumbra, 7×18 ‘Til Death Do Us Part, 7×19 Strange Bedfellows, 7×20 The Changing Face of Evil, 7×21 When It Rains…, 7×22 Tacking Into the Wind, 7×23 Extreme Measures, 7×24 The Dogs of War, 7×25 What You Leave Behind

This is it. The epic 9-part serialized conclusion to the Dominion War and Deep Space Nine . These final episodes wrap up every open arc on the show and are the very definition of essential viewing. For many, these episodes are arguably the best episodes of the series. The serialization is downright pioneering in nature and the tale being told is gripping. Not much else I can say. If I were you, I would block out a day and binge from here on out.

In Closing…

Creating this guide took quite some time, but nothing is perfect. I would love to hear feedback. Did I miss anything? Were any episodes a complete waste of time? Let me know.

I also couldn’t have done all of this by memory, so a big thanks to the folks at the astutely named  Memory Alpha for their extensive database on all things Trek. Even after rewatching every episode above, I always had the associated Memory Alpha episode entry open in another tab while writing this guide. A great resource.

And finally, for those of you who somehow made your way through 5,000+ words on the Dominion War, thank you! I hope that this guide provided some value to you. Thank you for taking the time out of your day to take a look.

Thank you so, so, so, so, so, so, so, so, so, so, so, so, so, so much for this! It was EXACTLY what I was looking for. I didn’t have time for the entire series, so using your guided plus a “top 10 DS9” I really feel like I was able to capture the heart of the series. Great job!

• Pingback: The 7 Best Star Trek DS9 Novels - TOME OF NERD

Can you do the same for the Borg story arc in Voyager?

Including Species 8472

That’s a great idea I’ve literally never thought about. I’m not as well versed in Voyager, but I’ve been looking for a reason to rewatch the series. We’ll see what I can do!

DS9 is my favorite Star Trek series and your list made it possible to go back and watch all my favorite parts of the series. I would suggest adding The Begotten S5 EP12 to the list. It details how Odo regained his shape shifting abilities.

Thank you for the kind words! I went back and forth on this episode. As you said, it’s very influential for Odo’s arc, but the episode itself isn’t related to the Dominion War. It might make sense as a supplementary episode because Odo being a shapeshifter is pretty essential to the overall story. Thanks for the feedback!

This is quite the devoted and curated list. I’d expect nothing less from a true Star Trek fan. I admire your work sir. Thank you for this. Coming from a 41 year old who watched these shows sporadically as a teenager but never got the full story arc. I am VERY much appreciative. Thank you.

Thank you for the kind words. Glad it was useful!

Damnit I should’ve been Jean Luc Pwncard. My whole life, ruined by less than 5 seconds of expounding upon a username… KHAAAANNNNN!

5×02 Is an absolute essential, it was the last chance to prevent the dominion war and it went horribly.

PS hottest Star Trek girl ever is a Vorta

Hello Nerd writer,

I’m a big fan of DS9 and was looking for a guide just like this, thank you.

I read your post about episode The Visitor. While our species, H. Sap., has a pre-existing condition of not seeing that we don’t know what we don’t know, as individuals we get to shine a little light sometimes so others can glimpse what we didn’t know we didn’t know.. uh, about something we thought we knew about.. if you follow me. Thx for your little light.

Thanks for reading and for the kind words!

I’d also add season 3’s ‘Heart of stone’ great now i got to go add it to my set

• Pingback: The Dominion War | Football Bats
• Pingback: DS9 Rewatch: Internment Camp 371 - TOME OF NERD

Thank you so much for taking the time to create the list! My husband and I are starting e17s7 today! Really appreciate awesome fans like you!

Thank you for the kind words! I’m glad you found it helpful.

I too would add Season 3 Heart of Stone. We get insight and further context into the Changlings – and also Nog and his entry into Starfleet Acadamy. I would add it to your Essential + Expanded + Supplementary list. It’s not required. But it’s a good supplemental episode.

Thanks, I’ll keep it in mind. Undoubtedly I’ll need to revise the list in the future because there are probably a few changes that could be made. Thanks again!

Also – thanks for these lists. I binged the show about 8-10 years ago and have been wanting to rewatch only the shows regarding The Dominion and The Dominion War. The Essential + Expanded + Supplementary list is great. I’m going to add in the recommendations of the others to this list. As I see them I’ll post my opinion – fwiw – as to if I agree or not to add them. Great Job!! I’m going to recommend your list to a friend. He’ll love it.

Thanks for reading and thanks for passing it along!

I think you made a mistake. You listed episodes 4×11 Homefront & 4×12 Paradise Lost as “essential”. But these episodes are actually 4×10 & 4×11 respectively. At least that is the way they are listed on Amazon Prime.

Actually this is kind of confusing. Wikipedia numbers the episodes for season 4 the same way you did here. But Amazon Prime & Netflix list them differently. Anyway…as long as you pay attention to the title for each episode you will be able to figure out the right episodes to watch. In any event, I appreciate this guide. I’m up to season 4 episode 26. Really enjoying it!! Thanks!

If I had to guess, I imagine the discrepancy comes from how The Way of the Warrior is listed. I’m going off of memory, but I believe Netflix has that as one long 90 minute episode whereas it aired as a 2-parter. So depending on if you count that as 1 or 2 episodes, it would affect the rest of the season numbering.

Thanks for the kind words!

You are correct. They list the 1st two episodes of season 4 together as 1 long episode. It does throw the rest of the season numbering off on Netflix & Prime. But thanks to you including the titles for each episode… its easy enough to figure out. Thanks Again. I really wanted to see the dominion war. But I probably would not have watched this series after all these years without this cheat sheet.

Been said before bro but top post, exactly what I was after, and your curation got it spot on for me. Cheers from London!

Thanks so much for this list! Awesome to have it, and great categorization of the episodes — best guide I’ve found!

This was an epic list to guide me in my first new apartment and projector binge watch. Bravo kind internet friend. May Stovokor gates be blown asunder from this glorious victory!! Q’apla!

i’m sure i would make other changes but 2 episodes I would add are (Spoilers):

1) Heart of Stone (3×14) – it’s when Nog applies to Starfleet. it’s been a while so i could be wrong but, without this episode some may go “ummmm…. what happened to nog” and then “when TF did Nog join Starfleet?”

2) Doctor Bashir, I presume (5×16) – this is the episode where it’s discovered that Dr. Bashir is genetically enhanced and thus, super smart and physically skilled. Before this episode, Dr. Bashir is, IMO, annoying and annoyingly naive. after this episode, he calms down and stops being so naive and i really like how they “fixed” his character. Without this episode, i can see people questioning why his character changed so much so fast. It won’t make sense IMO. not critical to the war but to one of it’s characters.

Thanks for the information and all the hard work you put in making this article, excellent 👌

thanks for the list, very helpful for rewatch

just what I need for a Picard-related rewatch, ty

Thank you so much for creating this guide! After starting to watch season 3 of Picard, I realized that not having watched all of DS9 was impeding my understanding of the return of the Dominion, and then I found your guide. I’m absolutely enthralled with DS9 now! My Dad always told me it’s the best science fiction series ever, yet I’d only seen the first three seasons, which are prior to this incredible Dominion arc. Just blown away. Right now I’m in season 5 and hitting even extra episodes like “The Begotten” (Odo with the infant changeling is emotionally compelling) and “For the Uniform” (because I got hooked on the Eddington storyline after he sabotaged the Defiant crew in “The Die is Cast”). I have this guide open at all times as I make my way through the Dominion War arc, so thank you!

The Waltz is the worst episode I’ve seen in the Dominion Arc. Dukat is all over the place, and I don’t see its importance to overall arc. I recommend removing it completely.

Thanks you for the terrific guide!

Sorry, I wrote that before finishing the episode. Now, I realize it’s the episode where Dukat escapes from Starfleet imprisonment. I understand its importance now.

I injured my knee and got a free trial of paramount and this list has been keeping me sane as I recover.

Thank you so much, OP.

Thank you so much for this. I actually only have interest in the Dominion more aspect for DS9 so this will be a perfect way for me to get caught up.

A nice concise list of episodes for the show. I have been looking for a trimmed list of DS9 for a while, this is definitely the best one. I have added a few more episodes, mainly around the Maquis and Emissary storylines which I find fascinating. Will definitely revisit the show more often watching it this way. Another show about a space station also benefits from a trimmed list.. Babylon 5. Happy to share it with you.

The 50 best Star Trek episodes ever

What kind of fools would attempt to take over seven hundred hours of television spread out over five different series, review them and then distill them down to a list of the fifty best episodes? You're looking at them. What follows is Empire 's breakdown of the best that Star Trek has had to offer over the past half century. Engage!

Here is a list of our favourite Star Trek episodes counting down from the 50th to the number one greatest. So sit back and get comfortable (this may take a while...)

50. Q Pid ( TNG )

John de Lancie's Q is a recurring pain in the arse for the crew of the Enterprise, but no one can say he isn't any fun. This time, when Picard rejects his offer to help mend some fences with a lady friend, he transports a number of the crew to Sherwood Forest, planting them straight into a Robin Hood adventure. Standout moment? An indignant Worf proclaiming, "I am not a merry man!"

49. Lower Decks ( TNG )

As The Next Generation was winding down its television run, the writers decided to shift gears and focus on a group of junior officers, following them as they interact with the primary crew while vying for promotions. An entirely different, very welcome change of pace that proves hugely enjoyable – despite a somewhat downbeat ending.

48. Endgame ( VOY )

Cut through all the technobabble and what you're left with is an intriguing tale of an older Admiral Janeway, 10 years after Voyager's return home, deciding to go back in time to help her younger self defeat the Borg and get her crew home from the Delta Quadrant before history unfolds the same way. It's no All Good Things , but it wraps things up well and gives Kate Mulgrew a real chance to shine in dual roles.

47. Hard Time ( DS9 )

In what is a dark take on TNG 's The Inner Light , O'Brien is found guilty of espionage by an alien race that implants the memory of years of harsh imprisonment, which in reality lasted just a few hours. Much of the episode is focused on his trying to readjust to his normal life. A bravura performance by Colm Meaney who sells the trauma spectacularly.

46. In A Mirror Darkly ( ENT )

Oh, Enterprise , why did you wait so long to live up to your own potential? This episode from the final season takes place in the Mirror Universe, serving as a sequel to season three of the original series' The Tholian Web and a prequel to that show's Mirror, Mirror. Imaginative and most of all fun, it's just unfortunate that executive producer Manny Coto couldn't tie the show further into the events of the '60s series.

45. Sacrifice Of Angels ( DS9 )

War brings a price, and the price paid on Deep Space Nine is very real. The conclusion of a six-episode arc opening season six, it's all about Sisko and his people reclaiming DS9 from the Cardassian/Dominion alliance. Tremendous action, espionage and yet another example (collect them all) of the way this series the consistently the best of the entire Trek franchise.

44. Phage ( VOY )

Executive producer Brannon Braga once said that Voyager should be The X-Files of space, and this episode shows it meeting that potential. An alien race in the Delta Quadrant, suffering from an incurable disease, prolongs the life of its people by transporting vital organs out of unwilling donors and transplanting them. It's chilling as hell, yet by the end – in true Star Trek fashion – you somehow end up feeling sympathy for them.

43. Balance Of Terror ( TOS )

The Federation's (and our) first look at the Romulans in what is essentially a submarine thriller in space. Mark Lenard (who would go on to play Spock's father, Sarek) is the Romulan commander who recognises many of his own traits in Kirk, finding him a worthy adversary. The exploration of bigotry (the Romulans are an offshoot of Vulcans) underpins a piece of television that manages to conjure genuine suspense as one commander attempts to outmaneuvre the other with only one possible outcome.

42. Relics ( TNG )

James Doohan reprises his original series role of Scotty in this Next Generation episode that sees Scott being rescued from the transporter of a long-missing transport ship and having to adjust to life in the 24th Century. The focus is strongly on Doohan and Levar Burton's Geordi LaForge, and serves as an effective exploration of ageism and the fight against obsolescence. One of Doohan's finest turns as Scotty, and while it's commonplace now (even in fan films), seeing Picard walk through a recreation of the original '60s bridge on the holodeck is very cool.

41. Arena ( TOS )

An alien race forces Kirk to fight the lizard-like Gorn, theoretically to the death, but the good captain refuses to carry out the fatal blow. By showing mercy, Kirk demonstrates the superiority of humanity, impressing the aliens and showing how far his race has come. It sounds simple, but the execution (despite the now infamously bad Gorn costume) is first rate.

40. The Offspring ( TNG )

In what could unofficially be viewed as a sequel to the season two TNG episode The Measure Of A Man , Data creates an android "daughter" (Hallie Todd's Lal) and attempts to instruct her in the ways of life. Moving on a number of levels, most notably watching Lal evolve in ways Data could never hope to as he fights to keep her free of Starfleet's science division. Co-star Jonathan Frakes made his directorial debut on this episode, paving the way to his taking on 1996's First Contact .

39. Past Tense ( DS9 )

As conceived by Gene Roddenberry, Star Trek was supposed to take modern social issues and examine them through the prism of the future. Embracing that philosophy, the writers of Deep Space Nine took on Los Angeles' growing homeless problem and postulated a frightening future (through DS9 's past) in which the homeless are herded into city sectors and all but abandoned there. Avery Brooks' Sisko finds himself having to step into history to make sure the time stream stays on course.

38. Datalore ( TNG )

Not everything in season one of The Next Generation felt like a retread of what had boldly gone before. Data's 'brother', an early model named Lore, shows up and Brent Spiner does a stand-up job portraying two very different versions of his character. Not dissimilar to the original's The Enemy Within .... which means that, yes, the plot is something of a retread, but in this case it's a very good retread. Okay?

37. Broken Bow ( ENT )

Enterprise comes out of the gate swinging with this two-hour premiere that efficiently sets up the series and establishes that the early stages of Starfleet were very different from what it would ultimately become. The promise of the show is nicely set up (disastrous theme song notwithstanding), but, sadly, it would seldom live unto it.

36. The Andorian Incident ( ENT )

The blue-skinned Andorians return for the first time since the original series and score in a big way. The plot – about a secret Vulcan plot against them – is interesting, but what crackles is the instant chemistry between Jeffrey Combs' (Weyoun on DS9 ) Shran and Scott Bakula's Captain Archer. It's a relationship that would serve Enterprise well for many episodes to come.

35. Little Green Men ( DS9 )

Now we know what went on in Roswell, New Mexico in 1947: A trio of Ferengi and a shapeshifter crash-landed in the desert and threw members of the US government into disarray. Deep Space Nine goes full-out comedy in what is this series' equivalent of The Trouble With Tribbles (aside from the episode that actually re-visits the Tribble episode, that is, but more on that later).

34. I, Borg ( TNG )

When a member of the Borg, eventually given the name Hugh, breaks away from the collective, it raises issues of whether or not genocide (to be accomplished by infecting Hugh and returning him into the collective) for the greater good is warranted. Seriously, when is genocide a good idea?

33. Duet ( DS9 )

A highlight of Deep Space Nine 's first Season, and essentially a two-person drama between Nana Visitor's Kira Nerys and guest star Harris Yulin as the Cardassian war criminal Marritza. Amazing back and forth moments between the actors, and riveting in the revelations that arise.

32. Time’s Arrow ( TNG )

An audacious adventure that begins with the discovery of Data's head among relics from 19th Century San Francisco and goes on to include aliens sucking the life force out of humans in the past, time travel, Whoopi Goldberg's Guinan and Mark Twain(!). It's utterly insane, but imaginative and enormous fun.

31. The Wounded ( TNG )

The Next Generation goes a bit Heart Of Darkness as Picard must stop a renegade starship captain from committing acts of war against the Cardassians, despite the fact that his military suspicions about them are true. Great tension as Picard is torn between his duty as a Starfleet officer and the grim reality of the political situation.

30. What You Leave Behind ( DS9 )

The two-hour series finale of Deep Space Nine . While far from the best series-ender ever, it's an exciting and moving close to a series that still had so much life left in it. Major arcs are brought to an end and entirely new ones are begun (and left dangling), but the most important thing is that the show left on its own terms and in its own way.

29. Unification ( TNG )

Leonard Nimoy's Spock comes to The Next Generation in what was a tie-in to 1991's Star Trek VI: The Undiscovered Country . The plot, about Spock's political attempts to reunite the Vulcan and Romulan people, is fine, but the joy comes from watching Nimoy interacting with Patrick Stewart's Picard. It is, in a word, fascinating.

28. Home Front/Paradise Lost ( DS9 )

Paranoia about changeling infiltration provides Admiral Leyton with an excuse to manipulate the militarisation of Starfleet against its enemy. It's up to Sisko and O'Brien to reveal the truth and preserve everything the Federation stands for. Not a million miles away from the plot of 2013's Star Trek Into Darkness , only better.

27. For The Uniform ( DS9 )

Once again the writers and Avery Brooks prove that Sisko is unlike any other Starfleet captain, as a tense game of galactic cat-and-mouse plays out between him and his former head of security Michael Eddington, who revealed himself to be a traitor and member of the rebel organisation the Maquis.

26. Future Imperfect ( TNG )

Jonathan Frakes gets to shine as Riker when he awakens sixteen years in the future in what are very different circumstances. Initially trying to adjust to this new life, inconsistencies lead him to try and discover the truth. As it turns out, nothing is as it seems. Certain elements play like an homage to Star Trek 's first pilot, The Cage .

25. Year Of Hell ( VOY )

A glimpse into what Voyager could (and should) have been: a gritty two-part adventure that follows the starship over the course of a year where it's constantly fighting for survival, and barely being held together. Disappointingly, It all gets reset at the end, but it's an incredibly dark journey and features a delightfully villainous Kurtwood Smith as Annorax.

24. This Side Of Paradise ( TOS )

Spock is able to reveal the depths of his emotion thanks to alien spores that have affected most of the crew, who are enjoying life on an idyllic planet. This also serves as a rare love story for Spock, and his final moment, once he's been restored to his logical self, is heartbreaking.

23. Our Man Bashir ( DS9 )

The name's Bashir. Julian Bashir. This homage to early Bond films sees the station's doctor in the role of a suave super spy, playing out a spy story in the form of a holosuite adventure (with very real consequences). The cast clearly had a whale of a time throughout, and with good reason.

22. Way of the Warrior ( DS9 )

For anyone who may not be enamoured with the early episodes of Deep Space Nine , this one should be your starting point. It's where the show becomes far more serialsed, tensions increase between the Federation and the Klingon Empire (paving the road towards the Dominion War), Michael Dorn joins the show as TNG 's Worf and Avery Brooks comes to life like never before as Sisko after he shaves his head and grows a goatee.

21. Space Seed ( TOS )

There's not much that needs to be said about this one beyond the fact that it marked Ricardo Montalban's debut as 20th Century genetic superman Khan Noonien Singh, and ultimately planted the seeds for what would, fifteen years later, become The Wrath Of Khan . The scenes between Montalban and Shatner (outside of a dopily resolved fist fight) are gold.

20. Q Who ( TNG )

From the imagination of executive producer Maurice Hurley came this Season Two episode that had John de Lancie's Q propel the Enterprise to the Delta quadrant where they encounter the Borg for the first time. One of the few episodes of TNG to reveal space to be a genuinely scary place.

19. Brothers ( TNG )

Brent Spiner does triple duty as Data, his brother Lore and their "father," Dr. Soong. The story itself — an attempt by Soong to provide Data with an emotion chip that Lore ultimately steals — is not half as memorable as the actor's three distinct performances.

18. Trials And Tribble-ations ( DS9 )

Now this was the way to celebrate Star Trek 's 30th Anniversary as the producers of Deep Space Nine crafted a story that took Sisko, Dax, Bashir and O'Brien and dropped them right in the middle of the original series' "The Trouble With Tribbles." Great fun and top-notch effects work that allowed this crew to interact with that one.

17. The Measure Of A Man ( TNG )

The first real evidence that The Next Generation was establishing its own identity as a series came in this Season Two episode. Picard defends Data's right to self-determination against a scientist who desires to dismantle him to create a number of similar androids. An insightful script by Melinda Snodgrass, and a standout performance by Brent Spiner as Data.

16. Chain Of Command ( TNG )

In this instalment of Keeping Up With The Cardassians, Picard is made a prisoner of war during a covert operation against the alien race. He's ultimately tortured by David Warner's Gul Madred, and the psychological machinations that follow provide some of TNG 's most powerful moments, and arguably Stewart's best performance in the role. "There are FOUR LIGHTS!"

15. The Enemy Within ( TOS )

Yes, you have to look beyond some stereotypical Shatnerisms, but overall William Shatner is stunning to watch in this episode as Kirk is, as a result of a transporter malfunction, split into good and evil duplicates of himself. A psychological study of the requirements for an effective starship captain. Written by Twilight Zone scribe Richard Matheson .

14. Scorpion ( VOY )

Often referred to by fans as 'The Breast Of Both Worlds', this two-parter introduces Jeri Ryan as Borg crew member Seven Of Nine, though her sprayed-on silver uniform wouldn't make an appearance straight away. Despite being a transparent attempt to 'sex up' the show, it was a tremendous introduction for the character and, more importantly, gave Voyager a much-needed kick up the arse in terms of both drama and conflict.

13. In The Pale Moonlight ( DS9 )

Starship captains have a tendency to bend the tenets of the Federation (we're talking to you, James T.!), but in this one Sisko pretty much snaps them in half as he manipulates the Romulans into joining the Federation in war against the Dominion. A powerful personal dilemma with no easy solutions.

12. Mirror, Mirror ( TOS )

Kirk, McCoy, Scotty and Uhura find themselves in a parallel, more savage universe where the Federation is the Empire and is essentially feared like the Klingons. Be sure to check out alternate Spock, who wears the goatee of evil.

11. All Good Things ( TNG )

The series finale of The Next Generation bookends its premiere, Encounter At Farpoint , as Q (John de Lancie) continues humanity's trial. Taking place in three time periods (the pilot, the present and the future), its scope is epic, its themes powerful and it's all so well executed that it probably should have been TNG 's first feature film.

10. The Inner Light ( TNG )

To ensure that memory of a civilisation survives its passing, a probe affects Picard's mind to make him live an entire lifetime among its people, while only minutes pass on the Enterprise itself. In three quarters of an hour, Patrick Stewart somehow makes you really believe in the love and loss of a life well lived – all in the blink of an eye.

9. The Doomsday Machine ( TOS )

A tense thriller that serves as a contrast in command between Kirk and Commodore Matt Decker (William Windom). After losing the crew of his ship, the Constellation, to a galaxy-roaming doomsday device, Decker is so driven by vengeance that he could very well sacrifice the Enterprise in its pursuit.

8. The Trouble With Tribbles ( TOS )

For the first time, Star Trek proved that it could be funny without losing any of its integrity. Purring furballs, Klingons, bar fights and great comic bits for Shatner to play all combine to make up a true classic. Remember: don't feed them!

7. The Visitor ( DS9 )

Jake Sisko grows up to be Tony Todd in this tale of Jake attempting to cope with the seeming death of his father, while being filled with the lingering hope that he may somehow be able to set things right. A stirring study of a father/son relationship and the weight of a guilt that spans decades.

6. Darmok ( TNG )

Quite possibly the perfect embodiment of the Star Trek philosophy. Two races, represented by Picard and the Tamarian's Dathon (whose people only speak in metaphors and cultural references), must bridge a language gap to establish relations between their people in what becomes a life and death struggle. Paul Winfield ( The Wrath of Khan ) guest stars as Dathon.

5. The Best of Both Worlds ( TNG )

After floundering for a couple of seasons, The Next Generation came into its own with the arrival of exec producer Michael Piller and this tale of the Enterprise's battle with the Borg, which features Picard's transformation into Locutus. From this moment on, resistance to TNG was futile.

4. Far Beyond The Stars ( DS9 )

Emotionally fragile, Sisko abruptly finds himself as science-fiction writer Benny Russell in 1950s New York. A tour de force performance by star/director Avery Brooks as Benny deals with the racism of the time. We're given the suggestion that the events of DS9 (and therefore the entire Star Trek universe) has sprung from his imagination. Added bonus: seeing much of the cast out of makeup.

3. Yesterday's Enterprise ( TNG )

The Federation is getting its arse soundly kicked by the Klingons in this time-altered universe, and Picard must figure out what to do with the Enterprise-C, a ship out of time whose arrival seems to have changed the course of galactic history. This (alongside Chain Of Command ) is about as gritty as TNG ever got and is hugely enjoyable as a result.

2. The Devil In The Dark ( TOS )

It looks like a shag carpet and has a vicious streak a mile wide, but it's actually a mother protecting its young from Federation miners. An episode that perfectly encapsulates the Trek philosophy of overcoming our differences and the personal favourite of Shatner, whose father died during filming.

1. The City On The Edge Of Forever ( TOS )

Starship captain meets social worker in the past. Starship captain falls in love with social worker. Starship captain sacrifices social worker for the sake of the universe. Social worker happens to be played by Joan Collins. Writer Harlan Ellison hates it, everyone else loves it. Star Trek at its absolute best.

In honor of Star Trek 's 50th anniversary this month, The Hollywood Reporter counted down the top 100 episodes of Star Trek — ranking them across all six TV series with help from the stars and writers who made them so beloved.

Now we're going to break it down even further — this time organizing the episodes by era. Every day through Friday, we'll be releasing a new list specific to each series, with the order is based on our original list of 100. 

Here, we look at the best of the original series, which ran from 1966-69 saw Gene Roddenberry's vision brought to life by actors William Shatner (Spock), Leonard Nimoy (Spock), DeForest Kelley (Bones), Nichelle Nichols ( Uhura ), Walter Koenig ( Chekov ), George Takei ( Sulu ), and James Doohan (Scotty).

Below you'll find Shatner and Koenig reveal their favorite episodes, as well as hear from  Star Trek Beyond director Justin Lin, two iconic Trek writers and many more.

"We had bee spending too much money by the network's reckoning, so we had less to spend on this particular episode," recalls Walter Koenig of the hour, which saw an away team forced to battle in an Old West-style gunfight. "It gave my character some interesting work. He got the girl, he died and came back to life. I loved the whole concept." 

'Star Trek': Walter Koenig on Lean Years After Cancellation and How Writing Ultimately Saved Him

"the galileo seven".

Not only does this episode give us the first appearance of a shuttlecraft in Trek lore, it introduces a version of the concept that would become key to the franchise decades later — that there is a push and pull between the needs of the many and the needs of the few. The Enterprise is on a mission to deliver relief supplies to a colony. Meanwhile, seven  crewmembers  — including Spock and Bones — crash land on a hostile planet, and Kirk must grapple with holding out hope for them and delivering the relief supplies. 

"A Taste of Armageddon"

"This was the first Original Series episode I ever saw and it still blows my mind," says Jordan Hoffman, U.S. Film Critic for The Guardian and host of ENGAGE: The Official Star Trek Podcast . "Kirk is escorting a diplomat to a system of planets that have been in conflict for centuries. However, to protect their society’s infrastructure and maintain their culture, they don’t fight with weapons. Computers determine where phantom missiles hit and if your number comes up, you are ordered into a disintegration chamber. It is up to the Enterprise to intervene (which they totally aren’t supposed to do) and stop this insanity. It’s a rich concept with thrills, action, great speeches and even some humor. (Indeed, Spock takes the time to make a solid joke before sending someone crumpled to the floor with his Vulcan nerve pinch.)"

"The Doomsday Machine"

If Star Trek had shown Starfleet at its best until now, audiences got to see the flipside in this episode, in which Commodore Matt Decker (William Windom ) turns into an outer space Ahab chasing the cosmic Moby Dick of the episode's title: a "planet killer" that had nearly destroyed his own ship and killed everyone on board except for him. For an episode with such stakes, it's a surprisingly subtle story: While we should be worried about whether the planet killer can be stopped, the real tension comes from watching Decker struggle to deal with his trauma. 

"The Corbomite Maneuver"

The first episode to be filmed after the two different pilots for the series, " Corbomite " manages to sum up everything that makes the original series so special, with a tense yet optimistic take on the idea of first contact between the Enterprise and an alien race that shows how fearless, compassionate and sneaky Captain James T. Kirk can be when pressed, and a Twilight Zone -esque last-second twist. As if that wasn't enough to make this episode worthwhile, it features the first times that DeForest Kelley and Nichelle Nichols played McCoy and Uhura — although by the time the episode aired, they were well-established characters to the loyal audience.

"Journey to Babel"

"I've always loved 'Journey to Babel,' by Dorothy Fontana," says writer David Gerrold when asked about his favorite Star Trek episode. "Because it reveals so much about Spock, and his past, and his parents." That's putting it mildly; before this episode, it's unlikely that anyone would have given much thought about the parents of any of the crew, but the introduction of Spock's estranged parents — one of whom was human, the other suspected of murdering a fellow diplomat on board the Enterprise — changed the way audiences looked at the characters forever: suddenly, they were more than just their jobs, and had inner lives and struggles that everyone could relate to. And all because the most alien of all of the crew had proven himself to be just as human as the rest of us.

"All Our Yesterdays"

While the final episode of the original series — "Turnabout Intruder" — is generally considered to be a low point for the show, the second last episode throws Spock, McCoy and Kirk back in time and puts them all out of their comfort zones as a result, with McCoy having to be the practical one, Spock becoming overwhelmed by emotions and Kirk on his own against the authorities. Yes, the title sounds like a soap opera (It's actually from Shakespeare, specifically Macbeth ), but this is a particularly strong Star Trek episode through and through. 

"The Enterprise Incident"

Justin Lin, who directed this summer's Star Trek Beyond , picks this tale of intrigue as his favorite. 

"A good old-fashioned spy thriller set in the Neutral Zone. What’s not to love?" Lin asks. "We get to see my favorite version of Kirk: the tactician. His ruse is brilliant and daring, but it’s Spock who steals the show in his interaction with the female Romulan commander. We see him in rare form, opening up his human and—dare I say—sexual side. Of course, Kirk’s ploy succeeds and the cloaking device is stolen, but Spock derides the fleeting nature of such military victories and says to the female commander something emblematic of everything great about Star Trek : 'I hope that you and I have exchanged something more permanent.' "

The episode was loosely inspired by a real-life incident where the USS Pueblo was attacked by North Korean forces after being accused of sailing into its territory in January 1968.

"The Menagerie"

Mr. Spock commits mutiny on the Enterprise in order to get Christopher Pike, his former commander, back to the forbiden planet  Talos IV.  We eventually learn that years earlier, Pike and Spock visited the planet, where Pike was horribly mutated — and Spock is trying to get his former commander there to be healed. 

"It is a story of Spock’s loyalty to his former commander as well as to Captain Kirk and of Spock’s bravery as he risks his own career and reputation," recalls Adam  Nimoy , son of Leonard  Nimoy  ad director of For The Love of Spock , which hits theaters Sept. 9. "Although he refuses to admit to it, Spock sets aside logic to do the right thing, and I just loved it."

How Nearly Refusing 'Star Trek III' Reinvigorated Leonard Nimoy's Career

"amok time".

For fans who'd spent the show's first year swooning over Leonard Nimoy's pointy-eared alter-ego, second season opener "Amok Time" was everything they could've hoped for and more: Not only did they get to go back to Spock's home planet, they also got to see two things they'd dreamt of but never expected: Spock in the throes of passion — apparently, Vulcans are very like dogs in heat every seven years — and Spock fighting Kirk to the death … or, at least, that's what it seemed like at the time. Written by noted sci-fi author Theodore Sturgeon, this episode showed that Trek 's second year would be, if anything, even bolder than its first.

"The Devil In The Dark"

"The Horta has a funny story," says original series story editor D.C. Fontana of the episode's alien. " Stuntman , actor, creature creator Janos Prohaska  did creature work for us. [Writer] Gene Coon, Gene Roddenberry and I were in the office and Janos came in and said, 'Come outside, I want to show you guys something.' So we went outside, and here's this a lump of what looked like foamy bubbles. He said, 'Just watch,' and laid a rubber chicken out on the street, and crawls into this rubber bubble suit and crawls towards the rubber chicken and the chicken disappears and a trail of bones comes out the back. Roddenberry , Coon and I were laughing our heads off, and Gene Coon said, 'I've got to do something with that.' "

That something turned out to be the Horta , an alien threat who isn't so sinister after all. 

"You think it's a monster killing the miners, and you find out it's a mother protecting its young!" says Fontana. "That was the first time we did the Vulcan mind meld, and that turned out well, but we also found that this alien isn't what you think it is. There's a human aspect that we can understand and begin to work with this thing."

"The Naked Time"

[youtube https://www.youtube.com/watch?v=M58aP5DtNqY]

A swashbuckling (and shirtless) Sulu is perhaps the single most enduring image from the original series, with the officer infected with a virus provoking him to act out his inner most desires. George  Takei  had just three weeks of "frantic fencing lessons" to prepare for his scenes, he recalled in his 1994 autobiography, To The Stars . Days before shooting, director Marc Daniels dropped another surprise: he would be performing the scenes shirtless. "Straightaway, I got down horizontally on the floor, put my feet on the couch, and began pumping out push-ups to build up a photogenic chest," Takei  recalled in his book.

"Where No Man Has Gone Before"

[youtube https://www.youtube.com/watch?v=QT4fm0f2lZY]

After the first Star Trek pilot failed to catch fire, Roddenberry enlisted Gary Lockwood, who was about to shoot  2001: A Space Odyssey  and had worked with the Star Trek creator on  The Lieutenant. Trek producers believed Lockwood's involvement could help seal the deal — and they also brought on a new captain (Kirk) as well as Mr. Scott and  Sulu . In the story, Kirk must grapple with the value of human life after an old friend and shipmate Gary Mitchell (Lockwood) gains dangerous (and growing) power from the edge of the galaxy. 

"The pilot sells, and 20 years later Roddenberry said to me that Gary Mitchell was the character that got Star Trek on television," says Lockwood. 

[youtube https://www.youtube.com/watch?v=4SK0cUNMnMM]

On the surface, it's an episode about Kirk fighting a giant lizard man, but it's about so much more. Namely: humanity, ingenuity and ultimately, mercy. After being forced to fight to the death, Kirk spares the life of the  Gorn . Those impressive Gorn sounds were courtesy of Ted Cassidy, best known as Lurch on another ' 60s classic,  The Addams Family . The image of Kirk fighting the Gorn is so indelible that even if you don't know the alien's species, you know his green skin.

"The Trouble With Tribbles"

[youtube https://www.youtube.com/watch?v=B2T1QX7BEyg]

Writer David Gerrold credits his interest in ecology with the origins of this classic episode. "I'd heard about rabbits getting out of control in Australia," he remembers, " and I thought, this is a very weird, very funny effect of introducing an invasive species into an environment without an appropriate predator. So, I was thinking for Star Trek , not all the aliens we meet are going to be scary or ugly — some of them are going to be cute and friendly and we're not going to recognize what kind of danger they are until it's too late." The teleplay was Gerrold's first professional credit, and he worked hard to make it the best that he could. "I had studied the Star Trek structure very carefully and put every scene on a 3 by 5 card until each scene demanded that the next scene followed," he says. "As funny as the script turned out, I was proudest of the structure of the episode. You could take all the jokes out, and it would still work as an adventure."

"Let That Be Your Last Battlefield"

[youtube https://www.youtube.com/watch?v=STQNi7ArRl8]

It's understandably challenging for William Shatner to pin down a favorite episode among all the greats, but when pressed, he chooses this one. The hour sees guest star Frank Gorshin play an alien, whose face is half black and half white and who hates those of his species with the colors reversed. 

"That beautiful concept, without shaking a finger, illustrated the ridiculousness of race hatred, and it was very entertaining as well. The magnificence of the idea is obvious," says Shatner . The actor says part of the brilliance of Trek is its ability to entertain without preaching.

"We use to say, 'You send a message by telegram. Make [your show] entertaining," says Shatner . "But when you can combine both, like that idea, it becomes both dramatic and obvious. And you become aware. Those were the best of the Star Trek episodes."

"Mirror, Mirror"

[youtube https://www.youtube.com/watch?v=_oOqQ38XLv8]If Star Trek gave anything to the world, it's the idea that evil versions of characters have goatees, an idea ironically put forward by the Spock of the Mirror Universe — who isn't actually evil , per se. That's a good thing, because if he had been, it's possible that Kirk, Bones, Scotty and Uhura might have been trapped in the morally-flipped alternate timeline for good, having to deal with the stomach-bearing outfits for women, the workplace harassment nightmare that is the Agonizer and George Takei's wonderfully over-the-top Evil Sulu for the rest of their fictional lives. A fun look at the roads not taken (including a more military-focused Starfleet), this episode would go on to inspire sequels in both Deep Space Nine and Enterprise . 

"Space Seed"

[youtube https://www.youtube.com/watch?v=B_c1Odol9xw]

No Star Trek episode has paid off quite like this one. Ricardo Montaban's single appearance on the original series as the 1990s  warlord Khan Noonien Singh set the stage for the undisputed greatest  Star Trek film ever, The Wrath of Khan , set 15 years after Kirk and the Enterprise stumbled upon the Botany Bay. "Space Seed" sees Kirk fight his intellectual and physical superior — and win despite the long odds. Nothing is more Kirk than that. 

"Balance of Terror"

[youtube https://www.youtube.com/watch?v=JGn948_PXTU]

The acclaimed episode was inspired by submarine warfare and introduces the Romulans , with whom the Enterprise engages in a claustrophobic game of cat and mouse. The episode tackles themes such as the futility of war and xenophobia, with Mr. Spock facing discrimination from his own crew when it is revealed that Romulans and Vulcans not only look similar, but also share a common heritage. 

"City on the Edge of Forever"

[youtube https://www.youtube.com/watch?v=KFqD7s-A6VU]

Never mind the behind-the-scenes controversy. Credited writer Harlan Ellison was heavily rewritten by  Roddenberry , D.C. Fontana and others before the episode was shot, and decades later sued CBS for a share of profits from the episode. Just enjoy one of the true classic hours of science fiction TV as a dazed and confused McCoy travels back in time and accidentally rewrites history, forcing Kirk and Spock to follow and learn firsthand how hard it is to do the right thing for the greater good.

"I knew this episode was going to be special, not because I’m prescient, but because a couple of months earlier, I had interviewed series creator Gene  Roddenberry  for the  Daily Sundial , the campus newspaper at San Fernando Valley State College," recalls journalist Fred Bronson, who would go on to form a friendship  Roddenberry . "Aside from telling me that the purpose of television was to sell toothpaste,  Roddenberry  talked about an episode that had been recently filmed that he said was good enough to be a motion picture — and long enough as well, as they had to delete a lot of footage in order to make it fit the hour-long slot."

For fans of unexpected celebrity appearances, the love interest in this episode? None other than Joan Collins

"The best episodes of Star Trek (or any series) were always the ones where you absolutely believed everything that was happening was real and that you were not being manipulated by the writer," says Bronson. " 'The City on the Edge of Forever' felt authentic from the opening scene on the bridge of the Enterprise to the heartbreaking ending, when Capt . Kirk must allow the love of his life, social worker Edith Keeler , to die in a traffic accident. For years, I couldn’t watch reruns of that final scene without bursting into tears. From Spock’s declaration that trying to create a mnemonic circuit in the America of the 1930s was working with 'equipment…hardly very far ahead of stone knives and bear claws' to Kirk’s explanation to a police officer that Spock’s ears were the result of a childhood accident involving a 'mechanical rice-picker,' the dialogue of this classic episode is etched in my brain as the story that will live forever as Star Trek ’s finest hour."

The best Star Trek episodes every Trekkie should watch

Boldly go where... we've gone before with the best Star Trek episodes of all time

On March 11, 1964, Gene Roddenberry wrote “Star Trek is…” onto a blank piece of paper. Fifty years plus later, the fan-favourite show continues to intrigue and innovative audiences the world over, and now with the excellent Star Trek Discovery reigniting our love for the sci-fi series, never have our expectations been higher… nor our craving for all things Trek greater.

With Discovery returning to our screens this week after it's mid-season break, I've ranked my favourite 23 episodes. Sure, some tough decisions had to be made (and of course, there have been some absolute stinkers that had no chance of making the shortlist!), but given the rich plots and stories from across fifty years of television, there's certainly plenty to choose from. No doubt there will be lots of 'discussion' about which episodes did and didn't make it in, so let me know your favourites in the comments below.

23. Family (The Next Generation)

Family is a defiantly low-key, but quietly radical, Star Trek story. Set in the aftermath of The Best of Both Worlds - which saw Picard forcibly transformed into one of the Borg - our favourite Earl Grey-loving captain returns to his ancestral home and comes to blows with his surly brother. Boring? Not a bit of it. This is Trek as a character drama, and an intelligent one at that. It's lack of plot only serves to emphasize how attached we have become to Jean Luc over the last few years, and how traumatised he has been by his recent fight.

22. Broken Bow (Enterprise)

Enterprise struggled to find its identity over the years. It had some great episodes and a lot of confused fluff, but there's no denying the confidence and strut of its pilot. Broken Bow sees the launching of the first Warp 5 spaceship and the Enterprise NX-01, and therefore the true beginnings of Starfleet. Captain Archer and his crew must take an injured Klingon back to Kronos, but get drawn into a mysterious time war that would go on to become an essential (if poorly wrapped-up) element of the series.

21. This Side of Paradise (Star Trek)

Lampooned in the years that followed, this is the famous "hippy" episode, where Spock comes under the influence of some local spores and falls in love with lovely Leila. Here's the thing, though; there's loads more to this episode than just the sight of Leonard Nimoy playing a very different sort of Spock and a drug metaphor. The love story is sensitively handled, and it's conclusion very affecting. There's some great dialogue (McCoy bellowing "Hiya, Jimmy boy! I've taken care of everything. All y'all gotta do is relax!" is a treat) and writer DC Fontana hones in on Spock's loneliness when he returns to "normal". And what could be more perfectly '60s than Star Trek meeting flower power?

20. Caretaker (Voyager)

It's safe to say that Voyager doesn't have the best rep among fans. New Star Trek had become such a part of the TV furniture by then that the shock of the new had worn off, and the franchise was badly in need of new ideas. That's not to say that there weren't good episodes, however, including the excellent pilot. Caretaker quickly sets up an intriguing status quo where Starfleet loyalists and a faction of rebel colonists called The Maquis are forced to work together when they find themselves trapped on the other side of the galaxy. Kate Mulgrew impresses as Captain Janeway, and the ship's medical hologram, played by Robert Picardo, is hilarious.

19. Magic to Make the Sanest Man Go Mad (Discovery)

Harry Mudd returns in this celebrated episode, using a crystal to lock the USS Discovery crew in time as they slip on their party clothes to unwind a little. In his efforts to keep the crew occupied as he explores the starship, looking for secrets and details to sell to the Klingons, Mudd's time crystal dooms the crew to die over and over, until Stamets - who exists outside of the loop - can convince Burnham of Mudd's plans and put a stop to them. It's a perfect, self-contained episode that explores not just time loops, but broader themes of love, loss, and greed. It also forever locks The Bee Gees as Trek canon.

18. Year of Hell, parts 1 & 2 (Voyager)

This one lives up to its name. This season four two-parter focusses on the Voyager as it is caught up in a running battle with the Krenim race. Over the course of months we begin to see the ship worn down, and its crew put through a string of disasters. It's almost - almost - Voyager's equivalent of The Best of Both Worlds with its dark tone and high consequences. Alas, it hits the reset button at the end of the story.

17. Space Seed (Star Trek)

Khaaaaaan! What more is there to say? This is the episode that introduced Roberto Montalban's devilish genetic superman, the man who would prove to be Kirk and company's greatest foe in the second Trek movie. It's more than just a dry run for that movie, though; there's a real sense of the crew being thoroughly tested by their new enemy. Although the episode ends with Kirk giving Khan a second chance, as we later discover, the world of Ceti Alpha V proves to be rather harsher than anticipated. That will come back to bite you, Kirk...

16. Arena (Star Trek)

AKA the one where Kirk is forced to wrestle a lizard. Arena is a truly iconic episode, homaged on Wayne's World and even JJ Abrams' 2009 Star Trek reboot. Vasquez Rocks in California are a stunning backdrop, a world away from the show's studio sets, and the Gorn captain is a fantastic adversary. What really makes it classic Trek however is the resolution, which relies on compassion and mercy, rather than brute force.

15. All Good Things... (The Next Generation)

Wrapping up a series as beloved as The Next Generation is a seriously tall order, but All Good Things... manages it with aplomb. It cleverly ties back to the very first episode, with John de Lancie's Q presenting the crew with another puzzle to solve, this time one that takes place in multiple time zones. The episode has an appropriate sense of closure, but with the movie series ahead of the Next Gen crew, this wasn't so much a goodbye as as a graduation.

14. The Vulcan Hello (Discovery)

The first series not to pivot the story around the captain, all eyes were on newbie Discovery and its opening episode, and it did not disappoint. Occurring a decade before the events of the original series, The Vulcan Hello introduced us to First Officer Michael Burnham - a human raised in a Vulcan world - and the Federation-Klingon Cold War. It showed us that Burnham's upbringing had afforded her with an unique insight... and she was not against bending the rules and going against orders for the greater good. It was beautifully followed up by its sequel, Battle at the Binary Stars.

13. Battle at the Binary Stars (Discovery)

Part two of Discovery's premiere, Battle at the Binary Stars, marks the first time the Federation and Klingons engaged each other in war (which was on stardate 1207.3, fact fans). Though the two powers had skirted around each other before, this was the first time there was open hostility, something Burnham was trying to avoid when she overpowered Georgiou in an attempt to open fire, unprovoked, on the Klingon vessel. It's a key event in the timeline of Star Trek, and adds great context to the Federation's on-going issues with Klingons that are still yet to come...

12. Trials And Tribble-ations (Deep Space Nine)

Designed to celebrate Star Trek's 30 anniversary, this glorious episode steps away from Deep Space Nine's traditional gloom and doom by flinging the cast back in time and into the original series episode The Trouble With Tribbles. The modern day cast appear to interact with the original icons in a hilarious, nostalgic, and brilliantly realised tribute to the show's origins.

11. Where No Man Has Gone Before (Star Trek)

Okay, so it's technically not the real pilot (that's actually The Cage which was rejected by NBC), but it marks Kirk's first appearance, and therefore the start of Star Trek as we know it. The Enterprise encounters the SS Valiant, a starship lost 200 years previously. Kirk's friend Gary Mitchell and the ship's psychiatrist, Dr. Elizabeth Dehner, are rendered unconscious as they fly through a magnetic storm. But when they awake, begin to demonstrate peculiar psychic powers. It looks a bit ropier than the main show and not all of the regular cast are in place yet, but it does show just how much of Star Trek was in place right from the start.

The 21 Best Star Trek Original Series Episodes, Ranked

"You know. 1966? 79 episodes, about 30 good ones," said Philip J. Fry of "Futurama" to the jarred, floating head of Leonard Nimoy. This is his animated opinion, of course, but a better question isn't how many are good, but how many of the original "Star Trek" episodes are great. Would you believe 21?

Determining greatness is subjective of course. Popularity isn't a fair indicator of quality, and some fan favorites are guilty pleasures, while others are fun but defective in ways that knock them down from great to merely good. Any episode's overall quality depends on multiple factors: the uniqueness of the premise, the quality of the writing, the story beats, the characterization, guest stars, action, music, production values, and even visual effects. 

Speaking of visual effects, we're not talking about the 15-year-old "remastered" CGI, which already look dated and cartoonish. We're going O.G. all the way. The criteria here is ranking these as the total package rather than the sum of their parts. With that in mind, here's a perhaps controversial list of the 21 greatest "Star Trek: The Original Series" episodes.

21. A Piece of the Action (Season 2, Episode 17)

Although humorous moments abound throughout the original "Star Trek," there aren't many outright comedy episodes. In fact, there are only three: "I Mudd," "A Piece of the Action," and "The Trouble with Tribbles." Most fans I know vote the straight "Tribbles" ticket, but that episode is merely cute-funny, whereas the over-the-top "A Piece of the Action," is actually genuinely funny. The script by Gene L. Coon is more absurd than "Tribbles" and features more comic business. The cherry on top was its helmer, James Komac, who was a gifted comedy writer and director of hundreds of episodes of shows including "Welcome Back, Kotter" and "Chico and the Man" (which he created).

This episode   is almost a meta-commentary and spoof on the "Star Trek" schtick of "strange new worlds" which end up being monocultures thinly based on Earth's history. Here we see why the Prime Directive exists: an entire civilization has modeled itself on the popular mythos of Roaring '20s Chicago mobs. It's literally Planet Cosplay, and an unintentional spoof of fandoms then and now. Two things keep it at this end of the list: it's shamelessly riffing on "Robin and the 7 Hoods" (1964), and it's almost irredeemably dumb. Fortunately, it's dumb fun, and fun enough to be among the best. "Right?" "Riiiiight."

20. Space Seed (Season 1, Episode 22)

You might be surprised that this comes in so low in a list of greats, but that it merits inclusion at all relies solely on the sheer screen presence and magnetism of its guest star. Khan Noonien Singh is an arrogant egotist and tyrant, but Ricardo Montalbán's confident performance makes him watchable. Minus him, the story defects would relegate this episode to merely "good." Many put this in their top 10, but I suspect that's because it basks in the reflected glow of its cinematic follow-up "The Wrath of Khan."

The script is serviceable but unmemorable and commits the sin of making our heroes foolish instead of making Khan's intelligence and cunning the real danger. Kirk hands this unknown and suspicious character unfettered access to the ship's technical library on a silver platter, and historian Marla McGivers is a pushover who betrays all her shipmates because she's a fangirl of brutish dictators.

Weak story aside, the episode does have strengths. All the performances are good, and the story moves along at a brisk pace. There's memorable dialog, and McCoy really shines when he isn't cowed by Khan holding a scalpel to his neck. There's also some of the best miniature effects work on the show, going to the expense of a custom-made model of the Botany Bay . Montalbán is what makes it a best episode at all, but he alone can't elevate it.

19. The Conscience of the King (Season 1, Episode 13)

This least "Star Trek"-y of "Treks" scores points for being just that. The series premise allows it to be a semi-anthology, able to shift genres without breaking format, so one week it's a psychological drama about the duality of human nature, another time it's about cold war proxies, or planet-killing doomsday machines by way of "Moby Dick," or — as in this case — a Shakespearean tragedy about mercy and revenge. Just As Hamlet must determine whether or not his uncle Claudius murdered his father, so must Captain Kirk determine if actor Anton Karidian is the man once known as Kodos the Executioner. 

Writer Barry Trivers cleverly frames his story within the play that informs it, a bit of dramaturgical license that permits a more theatrical approach. Take, for example, this bit of dialogue from Lenore Karidian: "There's a stain of cruelty on your shining armor, Captain. You could have spared him, and me. You talked of using tools. I was a tool, wasn't l? A tool to use against my father."

This episode exemplifies a shadowy aspect of Kirk's affairs rarely discussed in how he weaponizes romance to get what he wants. The ultimate irony is that he plays Karidian's daughter Lenore in order to get close to her father only to learn that she's been playing him. That it's so different is a double-edged blade that simultaneously makes it a best episode, but nowhere near the top. It was a great stretch for the show.

18. The Immunity Syndrome (Season 2, Episode 18)

This one barely edges out the not-dissimilar and more popular "The Doomsday Machine." Both feature the crew of a sister ship annihilated by a huge alien thing endangering life throughout the galaxy. But where "Doomsday" is a straightforward adventure story driven by an Ahab-like guest star, "Immunity" is more personal, as it features some great and properly motivated Spock and McCoy conflict. 

Too often Bones would goad Spock for no reason, but here their back and forth is professional: two scientists vying for an opportunity to study this alien organism, each feels himself the most qualified to take on what promises to be a suicide mission, and each, perhaps, choosing to make the sacrifice rather than let the other die. But it's Kirk who has to make the final, heartbreaking choice of which of his friends to send. That's classic "Trek."

Given its budget and the visual effects tech of the time, "Star Trek" was rarely able to get across truly alien life forms, but this is a notable exception, and the conceit that the Enterprise must enter the alien entity as a virus infects a cell is a nice twist. The visual effects of the space amoeba thing are fabulous and weird, something the 2007 remastered CGI does not improve on.

17. Day of the Dove (Season 3, Episode 7)

The third season has no classic episodes, but a few come close. "Day of the Dove" is the best of the bunch. The simple premise of exploiting bigotry between our heroes and their cold-war counterparts, the Klingons, works better than it ought. If you want to look for a message, the alien entity that fuels the very hatred and violence it feeds upon can be read as a stand-in for the military-industrial complex, which fans the flames of conflict in order to sell weapons in a perpetual feedback loop. Alternatively, you can just take it for a MacGuffin.

The nefarious influence of the alien entity memorably amplifies the slightest biases of the Enterprise crew, and it's uncomfortable to hear blatant racism coming of out our noble heroes' mouths, especially Scotty's attack on Spock. Michael Ansara plays Kang as no mere mustache-twirling bad guy, but as a shrewd enemy starship commander, an honorable warrior, and a fine opposite to Kirk. By turns personable, calculating, and violent, he's a model Original Series Klingon. Frankly, I'd rather watch him than Khan; your mileage may vary. It's got action. It's got character conflict for days. It's the best the third season has to offer, but it's not as great as the first and second-season entries coming up. 

16. Tomorrow Is Yesterday (Season 1, Episode 19)

The original "Star Trek" didn't play with time travel much, and when it did the results were either very good or they were horrid, with the backdoor pilot "Assignment: Earth" being the low point. "Tomorrow Is Yesterday" features the most offbeat teaser of the series, following an Air Force F-104 interceptor, with the visual punchline that the bogie it's after is the USS Enterprise. 

What follows is illogical as all get out, but the gimmick of the Enterprise being tracked as a UFO and having to undo the temporal damage it's done by being photographed and accidentally crushing that Air Force interceptor is great and the story milks it for all it's worth. No real depth here, but the fun is all in the plot events and reactions of the crew.

There's some great in-character stuff in the episode, including Spock's statement that he too doesn't believe in "little green men," and his one-star ranking of the Air Force film of the Enterprise as "bad photography." Kirk's playfully resigned responses to his Air Force interrogator are great, too. And, hey, Sulu even gets to get off the bridge. The main weakness is the "how does that work?" ending gimmick of beaming people back into their own bodies. Great, but not a classic.

15. Balance of Terror (Season 1, Episode 14)

A fan favorite for good reason, the episode depicts the loneliness of command as Kirk tries to seek and destroy a marauding alien vessel without triggering an outright war. Seeing some of the "lower decks" types makes the Enterprise feel more real and lived in and sells that Kirk's every decision has repercussions beyond the bridge. But it's Mark Lenard's perfectly pitched turn as the unnamed Romulan commander that's most memorable here. Torn over the ramifications of the performance of his duty, he's Kirk's equal in every way, and you can believe that he loses this battle not by dint of any personal failings but merely because his ship is outmatched by the much quicker and faster-firing Enterprise.

For 1966 the effects are great and largely still hold up. The Romulan ship is simple and distinctive, and the music is spot on. The main thing keeping it out of the top 10 is that it so baldly swipes elements of the films "Run Silent Run Deep" and "The Enemy Below," slapping pointed ears on the German Kriegsmarine story from the latter film, borrowing its war-weary commander and a subordinate fanatically loyal to their political leader. In "Arena," the show paid for the rights of the story it was cribbed from and credited the author. No such screen credit graces this obvious lift.

14. The Ultimate Computer (Season 2, Episode 24)

Kirk's infamous for offing overzealous computers (see: Landru in "Return of the Archons," Nomad in "The Changeling," and the androids of "I Mudd"), but his personal best computer kill is in "The Ultimate Computer." Here he doesn't merely meltdown the M5 Multitronic unit by confronting its flawed logic regarding its purpose; he aims a precise surgical strike at the chink he spots in its programming armor: appealing to the morality inherent in the memory engrams its all too human creator imprinted it with, causing it to reason it must die to pay for the sin of murder.

This episode is character-driven, with Kirk confronting his own redundancy and possible irrelevancy even as Spock and McCoy make their loyalty and friendship clear. Guest star William Marshall's turn as the deranged Dr. Daystrom is a standout, ranking among the best of the show.

All this drama is supported by some fine action, as M5 reduces a redshirt to a puff of smoke, photon torpedoes a robot ship, and then nearly destroys four sister ships of the Enterprise, actually killing the entire crew of one. Even the light ending — which often play as callous given the events which precede them in many episodes — is acceptable here because it's about Spock and McCoy, not Kirk. But it's still Kirk vs. the Computer, and those are never "Star Trek" at the very top of their game.

13. The Cage (Original Pilot)

Forget "The Menagerie" with its paper-thin envelope around the first pilot, repetitive courtroom scenes, and forced cliffhangers, all of which render it a solid but not great installment. But on its own "The Cage" is not just a great launchpad for what "Star Trek" is and would become, but an imaginative and well-executed story in its own right. Gene Roddenberry's script is smart, with the atrophied Talosian aliens a satirical stand-in for TV audiences who might rather live other people's fantasies than experience adventures of their own. While it's a bit talky and static in places, when they're in action it's great stuff — notably the laser cannon scene and Pike's illusory fight on Rigel VII.

Visually it's terrific. This was the most expensive episode ever made , and it shows. The sets, costumes, makeups, and many special effects are top-notch for a show of the era particularly the matte shot of the Rigel VII fortress. The pacing's a bit loose, the characters don't pop due to the largely meh casting, and "THE WOMEN!" Number One and Yeoman Colt secretly wanting to bone the Captain is cringeworthy. However, guest star Susan Oliver's performance is the standout here, followed by Leonard Nimoy as Spock. Ultimately, it's just as well that the far more energetic William Shatner stepped in to replace Jeffrey Hunter's less-than-charismatic version of Captain Pike .

12. Arena (Season 1, Episode 18)

If any episode of "Star Trek" is truly iconic, this is it. The action set piece on Cestus III is the biggest of any in the series, with running and jumping and explosions galore, a redshirt vaporization, a detonating tricorder, and a photon torpedo-sque mortar. Once back on the Enterprise, Kirk's dogged determination to overtake and destroy the enemy ship demonstrates the obsessive nature of his character, but communication with his alien foe plants a seed of doubt which ultimately empowers him to practice what he preached in "A Taste of Armageddon: " We're human beings with the blood of a million savage years on our hands, but we can stop it. We can admit that we're killers, but we're not going to kill today. That's all it takes. Knowing that we won't kill today."

Kirk doesn't kill, and it saves the day. It lands here amongst the best because the story ends with the overused first-season gimmick of the godlike entity — the others being Gary Mitchell, Charlie-X Evans and his Thasian truant officers, Trelane the god-child, and the Organians — but the Metrons are more a plot device than anything. The Gorn is a great and worthy adversary, even as its slow-motion gestures are laughable. Spock hanging a lantern on Kirk's cannon-building is a bit much, but hey, he's the costar and has to do something. 

11. Where No Man Has Gone Before (Season 1, Episode 3)

This might be a surprise but despite the second pilot weirdness of different uniforms, series crew regulars appearing not at all (McCoy, Uhura) or in different jobs (Sulu is an astrophysicist), and Spock's not-quite-there characterization and more severe makeup, the core "Star Trek"-ness is there in spades. Kirk makes a risky decision in the first act and must deal with the building consequences for the balance of the show, finally shouldering personal responsibility for his decision in the worst way possible: in order to save his ship and crew, he's forced to kill a subordinate shipmate and friend.

The episode looks great (being far more expensive than any regular production episode), repurposes the planet set built for the even more expensive first pilot, and features more optical effects than would be the norm for a production episode. Most importantly, William Shatner's Kirk projects leading-man charisma of the sort that's arguably what sold the show. It also delivers on Gene Roddenberry's original high-concept pitch of a "Wagon Train to the stars" where stories would focus on strong guest stars interacting with the recurring cast. The script is not without its flaws, and had Gary Mitchell been a tad more likable the drama would have played even better. Still, two thumbs way up.

10. A Taste of Armageddon (Season 1, Episode 23)

"New civilizations" planet stories rarely yielded great episodes, often setting up straw man civilizations for Kirk to knock down, but this one bucks the trend with a story smart enough to rank among the best. Kirk vs. the Computer legendarily has Kirk talk the machine to death, but now and again he goes for the direct approach. Here the computers coldly run simulations and select innocents to die, and Kirk has zero compunction about blasting them, finally forcing the two civilizations to finally attempt to negotiate peace after 500 years of a "war" where death has been made so neat and tidy they see it as a necessary evil rather than something to stop.

Goodies include Scotty's head-butting with Ambassador Fox, Kirk's arguments about war with Anan 7, and Kirk threatening to have the Enterprise rain destruction down on a planet that's not faced a real attack in centuries. The moral? Any war held at arm's length is mere statistics, something the American people had grown accustomed to until television thrust the reality of Vietnam into their living rooms each evening. That's a lesson we must learn over and over again in conflicts where we increasingly use long-range and smart weapons to strike people we never even see. It's a message as relevant today as when it was first aired.

9. The Corbomite Maneuver (Season 1, Episode 10)

Effectively the "third pilot" of "Star Trek," this was the first regular production episode to go before the cameras and it had the luxury of a rehearsal day, a solid director, and a fine script. It even ends with a quintessential "Trek" twist: our implacable foe ends up being an erstwhile friend. By rights, this should've been the first episode to air as it sets up the whole show, but it was nowhere near ready at the premiere , in part due to the sheer number of optical effects in post-production. Dr. McCoy is wonderful from his first appearance, and his camaraderie and professional conflict with Kirk set the stage for their entire relationship.

The weird flagship Fesarius is pure alien goodness, and the Balok puppet is iconic. Memorable business includes Sulu's countdown, Spock's logic and resulting lack of imagination, Scotty's comment about Spock's parents, and McCoy and Kirk's conflict over Bailey. A highlight is the briefing room scene, with its lived-in atmosphere with piles of tapes and empty cups of coffee showing instead of telling us how hard the crew has been working on their predicament. Likewise, the Enterprise feels like a real lived-in ship, with corridors bustling with the crew, something the show would lose as fixed costs increased and studio budgets didn't grow to match . It's one of the 10 best, held back only because it drags in some spots.

8. The Galileo Seven (Season 1, Episode 16)

Albeit loosely inspired by the survivor drama "Five Came Back" (1939), this episode charts its own course as Spock tries and fails to resolve a potentially lethal situation with logic alone. It's rare that adventure shows of the time would depict a lead character failing, but that's just what "The Galileo Seven" does. 

As in "The Corbomite Maneuver," we are again shown that Spock's logic can serve as blinders that prevent him from seeing all the possibilities even as he tells Scott "there are always alternatives." As such, he expects the giant natives to react rationally to a show of force and brings them right down on the party. He's likewise ill-equipped to deal with the emotional frailties of the crew under his command, especially the insolent and insubordinate Lt. Boma, memorably played by Don Marshall, later of "Land of the Giants."

The B-story with Kirk desperately trying to locate the lost shuttle against a ticking clock demonstrates the sorts of no-win scenarios a ship captain must face. The production scores visually for the full-size shuttlecraft, as well as the visual effects depicting it and its sister crafts' departure and return to the Enterprise hangar deck.

7. The Naked Time (Season 1, Episode 4)

The fourth episode aired, "The Naked Time" is the foundational character-building segment of the series, peeling away the surface of Kirk and Spock and revealing a bit of what makes them tick. It's also entertaining as hell, with a slow burn as the crew is at first blissfully ignorant of the inhibition-inhibiting compound brought aboard and then having to deal with the resulting chaos. Sulu's descent into madness is charming, and George Takei was always at his most charismatic when he got to play unhinged. Sadly, neither Uhura nor Rand's secret selves get explored, and poor Chapel's reduced to pining for Spock as her primary character trait for most of the series.

The only weak spot here is that the "science" part of science fiction went out of the airlock. A collapsing planet is as preposterous an idea as the notion that the Enterprise is forced to constantly alter its orbit to study it. But guest crewman Kevin Riley is fun and Scotty gets two great lines here, the first being "I can't change the laws of physics," and the second an example of technobabble that's simple and audience-friendly: "You can't mix matter and antimatter cold!"

6. The Devil in the Dark (Season 1, Episode 25)

The episode is unique for being the only one to open with no sign of the Enterprise or her crew. Effectively a redo of series opener "The Man Trap," this episode succeeds where its predecessor fails not merely because the crew act more rationally but because a narrative twist turns the titular "Devil" into a sympathetic character. The Kirk-Spock dynamic is on fine display here as Spock first wishes to capture the creature alive and Kirk wants it dead, but Spock's feelings for his captain override his desire for scientific knowledge the instant he believes Kirk is in danger. 

Spock urges his captain to "Kill it!" even as Kirk susses out that the creature may be more than a monster. This is the first instance of Spock mind-melding with a wholly alien life form, a gimmick which would be taken to preposterous extremes in "Star Trek: The Motion Picture." Leonard Nimoy's "pain!" emoting is a bit over the top even for the time and keeps the episode out of the top five. Otherwise, he and William Shatner display the chemistry that made the show work even when the scripts let them down. This script does not let them down.

5. Journey to Babel (Season 2, Episode 10)

This world-building episode fires on all cylinders and never misses a beat. If writers then or now needed a model for how to write "Star Trek," this is it, and it's hands down the best episode penned by Dorothy "D.C." Fontana. There's a story conflict as the Enterprise ferries quarrelsome ambassadors and their aides to the titular "Babel" conference over a matter of Federation business. There's an interpersonal conflict between not just Spock and his parents but also between Spock and Kirk and Bones over relinquishing command. 

There's physical conflict as ambassadors brawl, one is murdered, and Kirk is ambushed and wounded. We meet lots of aliens, see a bit of galactic politics, and get a nail-biter of a finish as McCoy tries to perform delicate surgery while Kirk struggles to keep it together amidst attacks by a seemingly unstoppable, unknown ship.

Mark Lenard returns not as a Romulan but as Spock's Vulcan father, Ambassador Sarek, who picks up on Leonard Nimoy's Vulcan portrayal and crafts one uniquely his own. Memorable too is Reggie Nalder, whose burn-scarred face and Austrian accent accentuate his alienness in the role of the blue-skinned Andorian delegate Thelev, and established Andorians as Federation members , who would not be explored on TV for decades. Spock's family drama is a bit conventional for an alien culture, and just a dash more of the Vulcan alienness we got in Ted Sturgeon's "Amok Time" would have made this perfect.

4. The Enemy Within (Season 1, episode 5)

With a script that takes a pinch of "Strange Case of Dr. Jekyll and Mr. Hyde" and adds a dash of "All About Eve," "The Enemy Within" really delivers on the "Star Trek" promise to be an "adult" show by exploring the uncomfortable idea that even the noblest have a dark side, and that our shadow selves are necessary parts of being human. The scenes with Kirk, Spock, and McCoy crackle with intellectual and emotional tension, and Spock finding Kirk's condition so "fascinating" neatly propels the drama while hinting at his own duality. William Shatner's twin performances as the understated compassionate Kirk and the scenery-chewing "imposter" demonstrate his range.

A few missteps are the weird editing, where events happen out of order, such as when Spock states they have an intruder aboard long after they've established the transporter duplicated the dog-thing; Rand being expected to stand up for herself in front of her alleged attacker, Kirk; and the silliness of Spock reporting that the malfunctioning transporter duplicated the thermal heaters beamed down and not thinking to beam down blankets or other insulation to help keep the stranded Sulu and company from becoming human popsicles. Additionally, Spock's closing crack at Rand about the imposter's qualities was and remains cringeworthy.

3. Mirror Mirror (Season 2, Episode 4)

This is the poster child for episodes that manage to become classics despite the premise being as dumb as a box of rocks. Absolutely nothing about the scenario makes a lick of sense. There's a parallel universe where all the same people end up on the same ship despite having vastly different histories and a culture of assassination. The starships in both universes happen to be on the same planet and beaming the same four people at the exact same time, and our parallel-universe leaping characters and their barbaric counterparts somehow switch wardrobes — and presumably underwear — mid-transporter beam.

What saves it is the sheer entertainment value of this gaudier imperial Starfleet and the skewed versions of familiar regulars inhabiting it. Evil Sulu's a sweaty seducer, mirror Chekov is a back-stabbing opportunist, and bearded Spock was a meme before we knew we had memes. The best Uhura performance can be found here, and Nichelle Nichols should be remembered for this over that overrated and involuntary interracial kiss. The only thing that could have made it better was had Yeoman Rand been brought back as "the Captain's Woman." The big speech to mirror Spock about the illogic of waste is Kirk at his Kirkiest, and that's the perfect capper on a perfectly entertaining classic that ranks right near the top.

2. Amok Time (Season 2, Episode 1)

The Vulcan episode to rule them all is one of those rare world-building episodes of the original series, except here the strange new world is Spock's home planet. Vulcan civilization is memorably introduced in a most unexpected way by demonstrating that the cooly logical Spock is anything but when it's time to swim upstream and spawn, whereas his mate-to-be, T'Pring , employs the logic Spock adores in order to escape her obligations to him and make her own choices. 

Everything about the scenes on Vulcan works splendidly, from matriarch T'Pau's officiating and T'Pring's challenge to the big Kirk-Spock battle. Okay, and the wonderful and memorable OTT music is the icing on the cake. The first half on the Enterprise has some nice comic moments as well as some solid Kirk-Spock-McCoy interaction, but, as with many episodes where a mystery is involved, the tension of the first half doesn't play quite as well on repeat viewings. 

Fortunately, the drama and conflict on Vulcan are top-notch and hold up. The punchline in sickbay is a classic, because the bigger the dramatic tension, the bigger the comic release, and, given all the action on the planet, the funny tag feels totally earned for a change.

1. The City on the Edge of Forever (Season 1, Episode 28)

No surprise here, as it tops a great many lists, but "City" excels not only because the core drama is compelling but because of the care with which it was put together. The most expensive regular production episode of the series , all the money is up there on the screen, from the period costumes to the backlot shooting, new sets, stock footage, and the flashing Guardian time donut. William Shatner, Leonard Nimoy, and DeForest Kelley are all in fine form here. Guest star Joan Collins isn't great but she's fine.

Story-wise, the fish-out-of-water situation, the incredibly high stakes, and the crushing inevitable tragedy make this the exemplary segment. Even gutted by ham-fisted staff rewrites by the "Trek" staff (in my opinion), Harlan Ellison's core story premise remains moving in spite of the on-the-nose sermon by Edith, the racist joke at Spock's expense, and the complete absence of the tragic Trooper character on whom the irony of who amongst us "matters" hinged. Kirk's episode-closing "Let's get the hell out of here" was not any kind of TV first, but it was the perfect minimalist button that the story needed. What more was there to say?

The best Star Trek series, ranked

Ready to settle in and watch some Star Trek episodes? Since there are so many, we’ve ranked all of the different series to help you get started on your quest.

Star Trek is one of the greatest franchises ever created. If you're new to the world of transporters and holodecks, you have so much wonderful content to catch up on — of course, some would say too much content.

Since there are over 850 episodes and counting (all of which you can stream on Paramount+ ), watching all of Star Trek can be more difficult than fighting a Gorn in the desert. To make things easier for you to get started, we've ranked every series (besides the short-form series Short Treks ) of this long-running franchise. Some of these choices were a bit daunting to play favorites with, but, like Jim Kirk, there's no belief in the no-win scenario.

Without further ado, here's our list of every Star Trek series ranked from worst to best.

11. Star Trek: Picard (2020–2023)

Star Trek: Picard was meant to be like comfort food to fans of Star Trek: The Next Generation . And whether fans were turned off by the changes in franchise direction with shows like Discovery or just wanted to see Patrick Stewart back in action, Paramount clearly thought this show would be almost universally beloved.

That didn't happen . The warm and fuzzy feeling of seeing a few familiar faces in the first season evaporated because of an often-confusing plot about androids. The second season continued this confusion with a time-travel story that often bordered on incoherence. While many Star Trek shows take a few seasons to hit their stride, it was shocking that so much of this relatively short series was seemingly created with "make it so-so" in mind.

10. Star Trek: The Animated Series (1973–1974)

If you're in the right mood (or you've been sipping on some Saurian brandy), Star Trek: The Animated Series has some wacky entertainment value. Any given episode had the writers throwing in stories like a giant version of a beloved character. And the animators threw some fun curveballs, including making the embodiment of evil into a shirtless hottie that would make even shirtless Kirk jealous.

However, this animated show was often caught between two very different worlds. It wasn't fully a return to the (relatively) grounded exploration of space, science, and morality of The Original Series . And it didn't fully lean into the chaotic possibilities of a cartoon world (something Lower Decks would later handle much better). So, while more and more elements of The Animated Series have become canonical thanks to shows like Discovery , and it's fun to hear the voice acting of the Original Series cast, this cartoon is one that all but the most hardcore fans can skip.

9. Star Trek: Enterprise (2001–2005)

Despite what you might have heard, Star Trek: Enterprise is not a bad show. It just didn't start as a very good show. The series was tragically canceled after the fourth season, which was arguably when it had just begun to hit its stride (thanks in part to longer story arcs and a really fun glimpse into Trek 's popular Mirror Universe).

At the end of the day, Enterprise is a show best enjoyed by Star Trek fans that like to pore over the Memory Alpha wiki and familiarize themselves with Trek minutiae. As a prequel show, it laid the groundwork for everything from Starfleet policy to alien interactions that other shows explore in more detail. If you don't have a shot at winning any Star Trek trivia contests at your local bar, it's still worth watching how captivating Scott Bakula can be in the captain's seat.

8. Star Trek: Prodigy (2021–present)

Star Trek: Prodigy was very difficult to rank. Unlike the other two Trek cartoons, this series was explicitly designed for younger audiences. Paramount clearly wants to use this show as a gateway for these younger fans to explore the wider world of Star Trek , but there are enough elements (most notably the return of Kate Mulgrew , reprising her role as Captain Janeway via a holographic form) to keep veteran franchise fans invested.

Ultimately, your enjoyment of this series will be largely dependent on how much you enjoy animated/YA entertainment. If nothing else, you should check out the first two episodes of this show to see just how beautiful the CGI animation can get.

7. Star Trek: Discovery (2017–present)

If Enterprise is the Star Trek show cut off too soon, Discovery may very well be the first Star Trek show to outlive its welcome, though it will end after its fifth season . There are many things the show gets right, from nifty effects to quirky characters to amazing casting (seriously, Sonequa Martin-Green is electrifying whenever she is on screen).

The show veers from a disjointed-but-interesting first season to a mesmerizing second season, which gets a real shot in the arm by introducing Captain Pike (played by the inimitably charming Anson Mount ) and Spock (played as a perfect homage to Leonard Nimoy by Ethan Peck). Later seasons, however, prove that the series can't get away from galactic-level threats, and character drama begins overriding plot development enough that we want to slingshot around the sun and return this series to its earlier roots.

6. Star Trek: Voyager (1995–2001)

Like many Trek series, Star Trek: Voyager had a rocky beginning, and it was often overshadowed by the excellent Deep Space Nine . Ironically, Voyager dramatically improved with what could be a cynical casting stunt: adding the alluring Jeri Ryan (constantly wearing a catsuit, no less).

Though it really looked like a desperate ratings stunt, Ryan turned the reformed Borg Seven of Nine into the most interesting character on the show. And, despite their alleged clashes behind the scenes, the actress helped to elevate every scene she shared with Kate Mulgrew. Between the new cast member, improved writing, and Mulgrew being nothing short of a damned icon, Voyager soon became appointment television, and it's definitely worth binge-watching for modern audiences.

5. Star Trek: Lower Decks (2020–present)

Lower Decks is an impressive show for many reasons, including the fact that its execution elevates its initial premise, which focuses on the lives of the lower-level staffers aboard the starship. Because showrunner Mike McMahan previously wrote for Rick and Morty and the animation takes its cues from the cartoon adventures of Rick Sanchez, many fans may have assumed Lower Decks would simply be " Star Trek meets Rick and Morty ."

Thankfully, that's not the case. Aside from animation similarities, the main element these two cartoons have in common is a breakneck, borderline chaotic pace. But as entertaining as it can be, Rick and Morty is an often nihilistic show with gags revolving around how nothing really matters. Lower Decks , however, is a lighthearted series that serves as the cure to modern Trek . If you've dismissed other contemporary series such as Discovery and Picard because they are grim, violent, and serious, Lower Decks is a wonderfully lighthearted alternative that is never afraid to poke fun at its own franchise.

4. Star Trek: Strange New Worlds (2022–present)

Star Trek: Strange New Worlds is a truly pleasant surprise to fans of the franchise. Set years before Captain Kirk sat in that famous chair, we see Capt. Christopher Pike (Anson Mount reprising the role) lead the U.S.S. Enterprise into bizarre adventures alongside some familiar characters (Ethan Peck returning as Spock, for example) and a few new ones.

Part of what helps this show shine is that it marks a return to episodic Trek in that every installment is a self-contained adventure as opposed to other newer series like Discovery and Picard , which build entire seasons around a single plot. The characters all ooze with the same swashbuckling charm of The Original Series characters, and we can't wait to see more of their adventures. We also can't wait to see more of Anson Mount's amazing hair (arguably the most awesome practical effect in the franchise).

3. Star Trek: The Next Generation (1987–1994)

Star Trek: The Next Generation has the dubious honor of being the first Trek show where veteran fans warn against new fans starting at the very beginning. Early episodes ranged from stupidly horny (planetary inhabitants in the episode "Justice" were barely wearing scraps of clothing) to ridiculously racist ("Code of Honor" may very well be the worst Star Trek episode ever made). Many of these problems stemmed from the fact that despite being called "The Next Generation," the show was trying to recreate The Original Series (right down to using some of the same writers and shamelessly reusing scripts from the scrapped Star Trek: Phase II series).

As fans like to joke, the show got better as Commander Riker's beard got longer. Season 2 was a major improvement, which was then usurped by season 3, which brought in new uniforms, new sets, and Michael Piller to head up the writing team. Just like that, TNG embraced its differences from its famous forerunner (Picard was cerebral whereas Kirk was impulsive, Data yearned for emotion whereas Spock detested it, and so on). At last, the gamble paid off, and the next generation of this franchise ushered in the next generation of Star Trek fans.

2. Star Trek: The Original Series (1966–1969)

What can we say about The Original Series that hasn't been said already? Gene Roddenberry successfully fused science fiction with American pioneer spirit to create his vision of this " Wagon Train to the stars." The episodes were both fun and thought-provoking in equal measure, and William Shatner as Kirk and Leonard Nimoy as Spock, among many others, turned in performances that seared themselves into our collective pop culture consciousness.

The Original Series offered social commentary about racism, imperialism, and (often to Spock's annoyance) the human condition. And the blend of big acting, ambitious sets, and poignant plots helped this show become something truly transcendent. The OG Star Trek shaped not only the future of the franchise but television itself, and it's not hard to see why it continues to win over new generations of fans year after year.

1. Star Trek: Deep Space Nine (1993–1999)

Placing Star Trek: Deep Space Nine in the top spot is perhaps a contentious decision. However, this series did more than measure up to the quality of The Next Generation (a lofty feat in and of itself). The show also made a number of storytelling and production choices that have helped DS9 seem more relevant in recent years than ever before, including tackling issues about race, religious fundamentalism, and war on a regular basis.

Perhaps the main way DS9 feels so pertinent is that the show broke the longstanding Trek rule of making only standalone episodes. As the powers that be focused more on creating their next show, Voyager , DS9 showrunner Ira Steven Behr was able to get away with creating long story arcs and frequent episode callbacks. The end result of this is that Deep Space Nine is the first of the pre-streaming era Trek shows that is perfect for binge-watching.

The 10 Best 'Star Trek' Episodes Ever

Best 'star trek' episodes.

With five live-action TV series, each ranging from three to seven seasons, there's been a ton of great "Star Trek" over the years. Here are 10 episodes — two from each live-action series — that we rank as the best. In each of these episodes, you're guaranteed to learn something about the "Star Trek" universe and, in some cases, even challenge your own moral beliefs about right and wrong.

10. "Regeneration," 2003 ("Star Trek: Enterprise")

The Borg's terrifying powers of assimilation are tough enough to face when you're in a starship with weapons on board. But what about if they were discovered on your own planet? "Regeneration" shows what happens when Borg are found above the Arctic Circle on Earth, facing a fairly unprepared group of people — remember, "Enterprise" is a prequel series and takes place just as starship travel begins. The creative methods "Enterprise" used in fighting the Borg are fun to watch.

9. "Equinox," 1999 ("Star Trek: Voyager")

As fans of the series know, the premise of "Voyager" is that the crew becomes stranded some 75 years' travel away from home. By Season 6, we are pretty confident that the crew has well assimilated (so to speak) this knowledge, but they come across a ship in the same quadrant that has more questionable methods in dealing with the problem. We see the stranded ship engage in subterfuge in this two-parter during the Season 6 finale and Season 7 premiere, which reminds us of how badly "Voyager" could have gone with a different crew. While "Star Trek" only touched on this theme briefly in "Voyager," mutiny by crews is also explored a few times in the series "Battlestar Galactica" in the 2000s.

8. "Borderland" / "Cold Station 12'' / "The Augments," 2004 ("Star Trek: Enterprise")

This incredible trio of episodes has some throwbacks to "Star Trek: The Next Generation" — mentions of Dr. Arik Soong, the grandfather of Data's creator, for instance — as well as the original "Star Trek," with some oblique references to the noted villain Khan . While these episodes came too late in the run of "Enterprise" to save the series from cancellation, they did show some creative flair with "Star Trek" lore, with the addition of references to genetic engineering, a hot topic in the current affairs of the time.

7. "Emissary," 1993 ("Star Trek: Deep Space Nine")

Pilots of "Star Trek" series are often unbearable to watch, but this one is an interesting exception. Viewers saw an interesting puzzle early in the two-part episode. The beloved Capt. Jean-Luc Picard of "The Next Generation" is portrayed as an enemy to Benjamin Sisko, the man considering taking the position of commander on "Deep Space Nine"; the conflict stemmed from a Borg attack and the death of Sisko's wife. There's nothing better than starting a new series with a moral quandary for fans to argue about. [ 'Star Trek' Stars Celebrate 50 Years of Hope at Comic-Con ]

6. "Living Witness," 1998 ("Star Trek: Voyager")

Writing history is never a neutral process, as there are so many viewpoints to consider. At times, countries must come to grips with the mistakes of their past that their ancestors may have actually believed were victories. In "Living Witness," the holographic doctor of "Voyager" is reactivated about 700 years after the series' events take place. He sees a museum exhibit that talks about the "warship Voyager" and some things the starship did that this museum portrays as extremely negative; the doctor then spends most of the episode trying to set the record straight, as he was there at the time.

5. "In the Pale Moonlight," 1998 ("Star Trek: Deep Space Nine")

Here, an Enterprise crewmember turns bad — but for the greater good. Commander Benjamin Sisko decides that he needs to bring the Romulans, a noted enemy of the Federation, onto the Federation's side to win a greater war. Immediately, the unprepared Sisko is thrown into a situation where he needs to ally with a Cardassian spy, a former prison convict and other unsavory characters to get the job done. We'll let you watch the episode to find out the conclusion, but let it be known that Sisko does break a few rules in his quest — and that he still thinks it's the best choice, even though he has some moral qualms about it.

4. "The Best of Both Worlds," 1990 ("Star Trek: The Next Generation")

The Borg — a race that assimilates everything that comes into its way into a vast collective — make an unexpected invasion of an area that is supposed to be reserved for the United Federation of Planets, which the USS Enterprise represents. Through a series of complicated events, the starship comes face-to-face with the Borg, and Picard is captured, ultimately becoming assimilated by the aliens. This season ended on a cliffhanger, with Picard — calling himself "Locutus of Borg" — ordering the USS Enterprise to surrender and assimilate. The cliffhanger, considered a huge shocker at the time, set up several other Borg-related episodes as well as the movie "Star Trek: First Contact" (1996). [ The Evolution of 'Star Trek' (Infographic) ]

3. "The Menagerie," 1966 ("Star Trek: The Original Series")

This two-part episode plays on our expectations of Spock, a logical Vulcan alien who usually runs things exactly by the book. In an uncharacteristic maneuver, the Vulcan kidnaps his former commander, Christopher Pike. He sets the Enterprise on course to Talos IV — a planet that Spock well knows is off-limits for Federation officers — and then Spock voluntarily assents to a court martial to talk about why. "The Menagerie" is noteworthy not only for playing with our expectations of reality but also for a creative use of old footage. A large part of the episode reruns parts of "The Cage," the original pilot for "Star Trek." That pilot was ultimately scrapped, and the series launched with an almost entirely rebooted set of main characters. [ What I Learned by Watching Every 'Star Trek' Show and Movie ]

2. "The Trouble with Tribbles," 1967 ("Star Trek: The Original Series")

Tribbles are an adorable species — fuzzy, small, almost like a spherical teddy bear — that have an unfortunate ability to reproduce. After the crew receives a single Tribble, generations of Tribbles quickly begin to take over the USS Enterprise, soon crowding the crewmembers out of their own quarters. Before long, the Tribbles start getting into the food stores and consuming anything edible on the Enterprise. The ultimate solution to the problem is creative. And don't worry — you don't see anything bad happen to these cuties. In the meantime, you can enjoy the hilarity, including a wonderful scene where a shower of Tribbles drops onto Capt. James T. Kirk's head.

1. "The Measure of a Man," 1989 ("Star Trek: The Next Generation")

"Star Trek" turns its attention to the android Data in a heartbreaking episode about how easily human rights can be disregarded for those who are a bit different. Data, we are informed, is going to be disassembled so that Cmdr. Maddox (a Starfleet cyberneticist) can study him. Data, naturally, is not pleased with this prospect and would like to resign, but he's told he can't because Starfleet considers him property. This sets the stage for a riveting legal drama, where Capt. Jean-Luc Picard represents Data's interests and Cmdr. William Riker is pressed into reluctantly representing Maddox's side.

The Best Episodes of Star Trek: Deep Space Nine , Ranked

When Star Trek: Deep Space Nine premiered 25 years ago, it was entering into a storied science-fiction enterprise that prized camaraderie and intellectual curiosity. Almost immediately, Deep Space Nine set itself apart from its predecessors. If previous incarnations saw their story lines born from a place of peace and exploration, Deep Space Nine was born of the fires of war. No incarnation of Star Trek before or since has lived up the ideals of diversity quite the way Deep Space Nine did over the course of its seven seasons. The series introduced the franchise’s first black lead in the form of Commander (and later Captain) Benjamin Sisko (Avery Brooks), a widow, single father, and religious icon to the Bajoran people who is tasked with bringing the newly freed people of Bajor into the Federation while heading a space station at the edge of a previously undiscovered wormhole. (If you want more details, take a look at my guide to every Star Trek show .)

Deep Space Nine isn’t only notable for its diversity though. The show favored long-form arcs, which allowed its stories to be as emotionally resonant as they were politically profound. It is a beautifully acted, impactfully directed, and resolutely gritty show. Rewatching Deep Space Nine in 2018 has shown me that its artistry feels more relevant than ever today, which makes a list like this difficult to write. In honor of its 25th anniversary, here are the top 15 episodes of Deep Space Nine, all available on Hulu .

15. “Past Tense Part 1 & 2” Season 3, Episode 11 & 12

Since its beginnings, science fiction has used all manner of ghouls, aliens, monsters, and madmen as allegory to interrogate real-world concerns. The Star Trek universe reflects this history, but in doing so, sometimes the complexity and tangled nature of certain social concerns get lost in translation. Deep Space Nine often made the bold decision to eschew allegory and instead tackle race, poverty, and identity with a more gimlet-eyed approach, which gave us episodes like the season three two-parter, “Past Tense.” In it, Sisko, science officer Lieutenant Jadzia Dax (a luminescent Terry Farrell), and Dr. Julian Bashir (the always amazing Alexander Siddig) are thrust about 300 years into the past because of a transporter malfunction. San Francisco in 2024 is a harrowing landscape in which the homeless are sectioned off from society, poverty is rampant, and racism is still very much a reality. It’s fascinating watching how each Starfleet officer contends with the thorny political moment as well as the lengths Sisko goes to ensure that the future remains intact. As men of color, Sisko and Bashir contend with racism in ways they never have to in their daily lives, as it is a thing of the past in Earth’s 24th century. As Robert Greene II wrote for the Atlantic , “‘Past Tense’ was notable for depicting racism not from the perspective of a well-meaning white liberal, as seen in previous iterations of Star Trek , but through the eyes of people of color directly threatened by violence and indifference.”

14. “Whispers” Season 2, Episode 14

What makes Deep Space Nine such an amazing series are its rich performances from a cast of actors with no weak links, adding an important dimension to the emotional reality of the series. This is true of everyone from silent supporting figures like Morn to crucial antagonists like Kai Winn to Starfleet officers like Chief of Operations Miles O’Brien (Colm Meaney), who was introduced on The Next Generation but came into his own on Deep Space Nine. Many episodes that focus on O’Brien put him through an existential, often surreal hell. “Whispers” is definitely part of that tradition, as O’Brien returns from an away mission to find his wife, Keiko (Rosalind Chao), and his colleagues treating him with strange suspicion. Taking inspiration from films like The Parallax View and Invasion of the Body Snatchers, “Whispers” creates a miasma of dread that builds to a gut punch of a surprise ending.

13. “Duet” Season 1, Episode 19

The first season of Deep Space Nine is notoriously rocky, as the writers and cast were still finding the right balance between acknowledging the history they were entering into and establishing the show as its own beast. “Duet” crystallizes the transcendence of the series as the writers smartly established the emotional lives of each character as important, making the political and historical commentary resonate on a deeper level. “Duet” fleshes out one of the best characters in the series, Kira Nerys (a fierce Nana Visitor), a Bajoran former freedom fighter (or terrorist, depending on who you ask) who now acts as the first officer aboard the station. She confronts the past of her people when a Cardassian she suspects to be a war criminal boards the station looking for medical help. “Duet” eschews any subplot to focus entirely on the morality play between Kira and a man she believes is responsible for hideous crimes against her people during the war. In doing so, it introduces a host of fascinating themes about the nature of war and its aftermath that are consistently explored throughout the run of the series.

12. “The Siege AR-558” Season 7, Episode 8

Despite my intense love of this series, I have a strange relationship with its final season. Most of that is because of the loss of my personal favorite character, Jadzia, whose final-season replacement lacks her complexity and throws off the balance of the narrative. But season seven has many stellar episodes, especially the barbed “The Siege of AR-558,” the darkest entry in the series’ exploration of the perils of wars and the moral compromises made in order to achieve victory. Sisko decides to help a group of downtrodden Starfleet officers fighting to protect an important outpost, and the episode is granted great dimension because of his willingness to cross lines to find success (along with the impressive guest turns). Coupled with the direction of Winrich Kolbe, who used his past as a Vietnam veteran to shape the visual grammar, it’s a thought-provoking and brutal episode that shows the depth of Deep Space Nine’ s moral complexity.

11. “The Magnificent Ferengi” Season 6, Episode 10

Deep Space Nine is typically considered a hard-hitting, gritty entry in Star Trek ’s canon. While this is definitely true, some of my favorite episodes are when it decides to embrace its pulpier sensibilities. Many of the most hilarious episodes center on the underhanded yet empathetic bar owner Quark (Armin Shimerman), and such is the case with “The Magnificent Ferengi.” In it, Quark forms a ragtag group of Ferengi to rescue his mother from the Dominion, the overarching big bad of the series headed by the Changelings. It’s a blissfully bonkers episode showcasing the comedic talents of the supporting cast, with Jeff Combs especially being a highlight. Plus, it has a guest turn by none other than Iggy Pop.

10. “For the Uniform” Season 5, Episode 13

At what point does the Federation’s interest in expanding a peacekeeping group of planets and influence turn into colonization? This is the question the franchise as a whole hasn’t properly considered despite the obvious military aspects to Starfleet and the writers’ interest in philosophy. Deep Space Nine tackles this directly through the arc of Michael Eddington, a Starfleet officer who betrays his duty while serving under Sisko in order to join a rebel group, known as the Maquis, disgruntled about the Federation’s practices.

9. “Sacrifice of Angels” Season 6, Episode 6

If I had my way, nearly the entirety of the sixth season would be on this list. It’s that good. The beginning of the season sees the main crew embroiled in a fierce war with the Dominion. “Sacrifice of Angels” culminates a crucial six-episode arc as Sisko makes a bold attempt to reclaim Deep Space Nine from Dominion influence. It’s bracing and profound, showcasing the most spectacular large-scale battle in Star Trek TV history. But it isn’t the bombast that lands the “Sacrifice of Angels” on this list, but how Sisko’s relationship with his status as a religious icon, a crucial arc to the entire series, evolves.

8. “The Sound of Her Voice” Season 6, Episode 25

“The Sound of Her Voice” has a deceptively simple premise: Aboard their warship USS Defiant, the main crew gets a distress call from a lone Starfleet captain (Lisa Cusak, voiced by Debra Wilson) on an inhospitable planet, who will die shortly if not given proper medical care. The crew slowly forms a relationship with Lisa, partially to keep her mind off what will happen if the Defiant doesn’t arrive in time, and also to talk about the interpersonal issues they struggle to voice with those closest to them. It’s a revealing, emotionally layered episode that creates worlds of intensity simply by characters having conversations with one another. Even more impressive is that Lisa is never seen onscreen. Debra Wilson is able to create a well-rounded, humane character with only the sound of her voice.

7. “Second Skin” Season 3, Episode 5

What if you woke up with a face that is not your own and told the life you’ve been leading is a cleverly constructed lie? From the very beginning, Kira Nerys is a complex woman who ties much of her identity to being a Bajoran — her role as a freedom fighter in the war to regain her planet provides the backstory to the series. “Second Skin” centers on Kira being kidnapped by Cardassians, whom she has long viewed as enemies given their long occupation of her home planet, and told she’s really a Cardassian spy who took over the life of the real Kira Nerys, and was implanted with false memories to make the deception more authentic. Tinged with a Philip K. Dick–inspired approach to identity, “Second Skin” further evolves Kira in ways that are both poignant and existentially profound.

6. “Improbable Cause” and “The Die Is Cast” Season 3, Episode 20 & 21

The former spy turned exiled Cardassian Garak (played with wit and cunning by Andrew J. Robinson) is by far one of the best characters in all of Star Trek canon. This two-parter from season three cements the moral complexity and sharp-tongued mendacity of Garak, giving Robinson the opportunity to take center stage as he tangles with the faults of his past. Brimming with intrigue, twists, and a standout interrogation scene between Odo and Garak, it’s a stunning two-parter that shows just how astounding Deep Space Nine could be with its characterization and sense of history.

5. “The Way of the Warrior” Season 4, Episode 1

If asked who my favorite Star Trek character is, I will excitedly and quickly name Lieutenant Commander Worf (played with fierce elegance by Michael Dorn), the first Klingon in Starfleet whose gruff exterior masks his intense honor and passionate nature. Worf joins Deep Space Nine in its feature-length season-four premiere, and he makes a perfect addition to the series as the Klingons make dramatic choices in order to fight the Dominion in the way they believe is right. “The Way of the Warrior” pushes Deep Space Nine to a new level of excellence. It encapsulates everything I love about the series: its lived-in quality, the honest yet never uniform emotional dynamics of the cast, its bracing sense of action, and its surprising wit.

Even better? This episode introduces the first inkling of my favorite love story in Star Trek history between Worf and Jadzia Dax, a Trill science officer who is joined with a symbiote who has lived several lives as men and women, giving her a radical view (for Star Trek at least) on gender and sexuality.

4. “Trials and Tribble-ations” Season 5, Episode 6

When I watch the best episodes of Deep Space Nine , an immense feeling of wonder wells in my chest. “Trials and Tribble-ations” is the most technically astute and narratively audacious of Deep Space Nine’ s episodes. The episode begins with the Temporal Investigation unit coming aboard the station to investigate the details of how the crew of the USS Defiant were flung back in time to stop the assassination of James T. Kirk, and crosses paths with the crew of The Original Series. Seeing Deep Space Nine cast members like Worf and Jadzia don the bright, tight-fitted costumes of the Enterprise’s crew to blend in is a pure joy to witness. Sisko and the rest of Deep Space Nine may seem to fit uneasily within the landscape of The Original Series , but this episode works beautifully, showing just how far Star Trek has come while acknowledging the greatness of its beginnings. No matter how many times I watch “Trials and Tribble-ations,” I am still in awe of its joyfulness, sense of play, and consideration of Star Trek ’s beginnings.

3. “In the Pale Moonlight” Season 6, Episode 19

There’s something about the bass in Avery Brooks’s voice and the the tension in his physicality that immediately communicates that Sisko is not the kind of man you want to cross. “In the Pale Moonlight” depicts Sisko’s willingness to bend his ethics in order to win the Dominion war that the Federation is currently losing. Told in flashback format, Sisko breaks the fourth wall, discussing how he enlists the help of the underhanded, yet well-connected Garak to convince the Romulans to enter the war on the side of the Federation. This is the story of a man selling off part of his soul and Starfleet values in order to accomplish what he feels is for the greater good. This is Deep Space Nine at its most ethically complex and morally gray. It’s the darkest entry in Star Trek history, pushing Gene Rodenberry’s creation to limits he likely never imagined. More than that, it is an astounding testament to the skills of actors Avery Brooks and Andrew J. Robinson.

2. “The Visitor” Season 4, Episode 3

I can say without hesitation that Deep Space Nine has the most moving, complex, and beautiful depictions of black fatherhood in all of television history. The relationship between the widowed Sisko and his teenage son, Jake (Cirroc Lofton), is tender and heartfelt. “The Visitor” depicts the depth of their love for one another after a freak accident on the USS Defiant seemingly kills Sisko, and Jake dedicates his life to finding a way to save his father. We watch Jake grow into a man (played with melancholy and yearning by Tony Todd) who becomes a writer and scientist watching his marriage disintegrate because of his harried quest to save his father. It’s an episode that embraces sentimentality without sacrificing complexity, and a long view of history without losing sight of the heartwarming relationship between Sisko and Jake at its center.

1. “Far Beyond the Stars” Season 6, Episode 13

When I rewatched “Far Beyond the Stars” last year, I was amazed at how its themes felt richer and more poignant. Directed by Avery Brooks, who gives his best performance as Sisko in the episode as well, it follows Sisko as he gets visions that he’s actually a 1950s science-fiction writer named Benny Russell, trying to write a story about a black captain aboard a space station called Deep Space Nine. There are many immediate pleasures to this episode, like recognizing Brooks’s skills as a director and seeing the cast outside of their usual costumes when they play people Benny crosses paths with in the 1950s. But “Far Beyond the Stars” earns the top spot on this list for its unflinching, layered portrayal of racism and police brutality, and Brooks’s raw performance, which perfectly encapsulates the emotional reality that comes with being black in America. Watching this episode in 2018, the undercurrents and concerns it depicts have only grown deeper in their impact. With “Far Beyond the Stars,” Deep Space Nine once again proves why it is one of the best science-fiction shows to ever air on television.

Star trek: the 10 best episodes of ds9 ever, according to imdb.

Star Trek: Deep Space Nine is one of the most beloved Star Trek series. What are the ten best episodes of the show, according to IMDb?

Almost 30 years ago, in 1992, Star Trek: Deep Space Nine hit television screens. DS9 boldly went where no Star Trek show had gone before at the time, with characters, storytelling, and settings far from what was seen previously. It has since become one of the most popular entries of the franchise.

Related: The Best Character In Each Season of Deep Space Nine

For seven seasons, the crew of the eponymous station and the USS Defiant entertained audiences with many adventures. These audiences have, in turn, spoken on which episodes were the best and highest rated according to IMDb.

The Die Is Cast (Season 3) - 9.0/10

Season 3 was when the Dominion as a superpower was introduced, but it was not until this episode and "Improbable Cause" that they returned in a big way. A joint Cardassian and Romulan fleet, headed by spymaster Enabran Tain, made a preemptive strike against the Dominion and their smart and devious Founders.  The tailor Garak also had to choose whether to side with Tain or Constable Odo.

"The Die is Cast" not only had repercussions for all of the major factions, but it was also strong on the characters. The emotional highlight was when Garak was forced to torture Odo to solidify his allegiance to Tain. That he was deeply hurt and regretful for doing it was an excellent example of how the characters of DS9 , even secondary ones, were developed well.

What You Leave Behind (Season 7) - 9.0/10

The ending storyline of  DS9 was a whopping nine episodes, with the series finale clocking in at 90 minutes. The final battle of the Dominion War was nigh, with all the significant players prepared to put everything on the line for victory. Captain Sisko was also about to face his destiny alongside the villainous yet beloved Gul Dukat .

The extended runtime guaranteed that "What You Leave Behind" wrapped up almost all of the character arcs and conflicts. Unlike other finales, there were no promises of more adventures as the beloved crew went their separate ways. It was a bombastic, heartwarming, and bittersweet farewell after seven seasons.

The Way Of The Warrior (Season 4) - 9.0/10

One of the essential aspects of DS9's predecessor, The Next Generation , was the modern reinvention of the Klingons into begrudging allies of the Federation. Worf thus was a crucial character, as he provided the audience more insight into his race. The fourth season of DS9 took the next step for both by reigniting tensions with the Klingons and reintroducing Worf as a series regular.

"The Way of the Warrior" raised the stakes for DS9 by adding the Klingons to the Federation's enemies alongside the Maquis Resistance. This was clear when Klingon ships were involved in two altercations against the Federation and the station itself. It also helped that this episode was also at a 90-minute runtime, which gave plenty of opportunities for Worf to integrate himself into the cast.

Far Beyond The Stars (Season 6) - 9.0/10

Halfway through Season 6, Sisko was crushed by losing many of his colleagues to the war. When he was considering resignation, he was transported to the 1950s and turned into a writer named Benny. With no memories of his former life, Benny went about his typical day and dealt with all the troubles and widespread social unrest around him.

While episodes of The Original Series and The Next Generation presented episodes around racism using allegory, DS9 cut to the chase and showed the truth of this period as is. "Far Beyond the Stars" was not only a powerful presentation of a sensitive issue, but it was also a significant examination into Sisko. It fitted that the episode, in 1998, aired during Black History Month.

Call To Arms (Season 5) - 9.1/10

After the events of the two-parter "In Purgatory's Shadow" and "By Inferno's Light," the newly-formed Dominion-Cardassian alliance made only a few scattered appearances to menace the heroes in a cold war-like fashion. This all changed by the season's end when more Dominion forces arrived to bolster their numbers. To Deep Space Nine, it was clear that war was inevitable.

Season-ending, multi-part cliffhangers were popularized by The Next Generation , but DS9 handled its season finales differently. In the case of "Call to Arms," it wrapped up the simmering hostilities with the Dominion and set the stage for Season 6 by showing the opening salvos of the Dominion War. It was a very effective finale that guaranteed Season 6 would be a whopper.

Sacrifice Of Angels (Season 6) - 9.1/10

The first six episodes of Season 6 formed a storyline of the DS9 cast scattered, with some forced to abandon the station. Others stayed behind and were forced to endure the occupation of the Dominion. With the start of the Dominion War not going well for the Federation, Sisko provided the only option to give the Federation a fighting chance: Retaking Deep Space Nine.

This episode was given the task of concluding the introductory arc of Season 6, and for the most part, it succeeded. The battle to retake the station was a thrilling action sequence, and it foreshadowed what was to come for the rest of the season. Even the primary villain, Dukat, had intense character moments and is the reason this episode was called "Sacrifice of Angels."

Duet (Season 1) -  9.1/10

The initial premise of  DS9 was for the Federation to assist Bajor after decades of brutal oppression from the Cardassians. Major Kira, a former freedom fighter, was outraged when a Cardassian linked to an internment camp visited the station. However, things took a turn when the Cardassian was not all he appeared to be.

"Duet" was the first to spotlight the Bajoran Occupation, and Kira's stories and parallels to World War II are haunting and tragic. However, the performance of guest star Harris Yulin as the Cardassian Marritza deserved a standing ovation. The episode's placement in Season 1 was vital because it was just the start of DS9's popularity for years to come.

The Visitor (Season 4) - 9.2/10

One thing that made Sisko stand out among other captains was his son, Jake. This episode was a tale of Sisko being killed in a freak accident. What followed was Jake trying and failing to move on with his life as he obsessed over bringing his father back.

Related: Tony Todd's Best Movie Roles, Ranked

Despite being credited as a primary cast member, Jake, and his actor Cirroc Lofton, did not appear as often as the other characters. "The Visitor" allowed Lofton to shine in this tearjerker episode on the love between father and son. Particular praise goes to  Candyman icon Tony Todd, who portrayed the elderly Jake and gave a stellar performance.

Trials and Tribble-Ations (Season 5) - 9.4/10

In this 30th anniversary special, what started as a routine trip took an unexpected turn when the USS Defiant was thrust back to the past by a Bajoran artifact. To make things worse, they were brought back to the time of The Original Series . To make things even worse, the mastermind of this plot had one nefarious goal: the assassination of Captain Kirk.

The respect and reverence "Trials and Tribble-ations" had for The Original Series was evident when the DS9 cast infiltrated the USS Enterprise. It was the perfect anniversary celebration for Star Trek and   one of its best crossovers . Even 25 years later, the effects used to make this episode a reality combined with the original "The Trouble with Tribbles" is remarkable.

In The Pale Moonlight (Season 6) - 9.5/10

As Season 6 progressed, it was evident that the Federation may have retaken Deep Space Nine, but the Dominion War was far from over. The Federation was far from winning, with the causality count increasing. Only by getting the Romulans involved could the Federation have some chance at victory, but the problem was convincing them.

DS9 was considered the darkest Star Trek series, and this episode helped solidify that. Through flashback segments and his log, Sisko laid bare the lengths he went to give the Federation a chance to win the war. It perfectly encapsulates all the strengths and risks DS9 took, and it is no surprise why "In The Pale Moonlight" is ranked by IMDb as the best episode.

Stuck in a Loop: The Best of Star Trek's Time-Jumping Episodes

From The Next Generation to Discovery, going around and around is sometimes very revealing.

StarTrek.com

In the Star Trek: Discovery Season 5 episode, " Face the Strange ," Captain Burnham and Commander Rayner find themselves both stuck in a loop, but also, jumping all around the timeline of the titular starship. From the point before the U.S.S. Discovery was launched, to pivotal moments in Season 4, Season 3, Season 2 and even very early in Season 1, Rayner notes at one point that, "We’ve gone back in time to when you went forward to the future. That’s a little confusing."

Throughout all of Star Trek 's history, time travel has been just as propulsive to the narratives as space travel. But, within the various time travel stories of Trek , there is a special kind of time-skipping episode — the time loop story. Discovery has recently shaken-up this formula with "Face the Strange," but many elements of this episode pay homage to a proud Star Trek tradition. Here’s the history of the best time loop, and time-jumping episodes across the entire Final Frontier.

" Cause and Effect ," Star Trek: The Next Generation (Season 5, Episode 18)

"Cause and Effect"

Perhaps one of the greatest science fiction episodes of all time, The Next Generation set the gold-standard for how to do time loop episodes.

When the Enterprise collides with another starship in the first scene, this episode poses one question right off the bat: What happens after you blow up the ship — and everyone on it — before the credits roll? The answer is mostly connected to whether or not we can even remember when we're stuck in a loop. Without actually spoiling this classic episode, let's just say thank the stars for Dr. Crusher and Data.

The brilliance of "Cause and Effect" cannot be overstated, but the 21st Century legacy of this episode is utterly appropriate. When Geordi reveals how the time loop works, Riker says, "You mean we could have come into this room, sat at this table and had this conversation a dozen times already?" This scene has become a popular meme format across various social media platforms, satirizing the time loop of some aspects of the internet experience.

" Parallels ," Star Trek: The Next Generation (Season 7, Episode 11)

"Parallels"

Arguably, when Worf starts slipping between realities in "Parallels," the story is more focused on other dimensions, rather than a true time loop. But, each time he pops into a new reality, Worf does tend to reply to his own personal log, which is what began the episode.

Obviously, in each new timeline, Worf's personal log is different, and because he checks it so often in the episode, this gives "Parallels" the feeling of a time loop story, even though Worf is technically moving both forward in time, and also, side-to-side.

On top of all of this, "Parallels" feels time-loopy because so many ideas and plot points from previous seasons of The Next Generation are revisited here. From references to " The Best of Both Worlds ," to the return of Wesley Crusher, "Parallels" brings all the good things of TNG back around again for another look, from a different point of view.

" All Good Things... ," Star Trek: The Next Generation (Season 7, Episode 25)

"All Good Things..."

Speaking of the best of The Next Generation , the immortal series finale is, from a certain point of view, one big time loop. As Jean-Luc Picard shifts between past, present, and future, the biggest mystery of "All Good Things…" is what caused the anomaly in the Devron system? Eventually, we learn that the ending and the beginning of this story are inextricably connected, a paradox that creates a kind of loop that must be broken.

Twenty-nine years later, in the Star Trek: Picard episode, " Imposters ," Captain Liam Shaw references this moment, and notes that Picard and Riker have a "real chicken and egg thing going on." It doesn’t get any more time-loopy than that!

" Visionary ," Star Trek: Deep Space Nine (Season 3, Episode 17)

"Visionary"

When O'Brien starts seeing another version of himself appearing randomly throughout the station, Dr. Bashir briefly floats the idea that he's just having really boring hallucinations. But, as the episode goes on, it becomes clear that O'Brien is actually seeing brief moments in the future, and then, catching up to those moments in the present.

"Visionary" messes with what we expect from a time loop episode, because in all instances of future occurrences, there are literally two O'Briens present, and, when the past O'Brien catches up to the future moment, the duplication effect happens again, creating a kind of visual loop for the audience. The funny thing is, in several instances, the future doesn't play out exactly the way past O'Brien saw the first time, making this one of the wobblier time loops in all of Star Trek .

" Relativity ," Star Trek: Voyager (Season 5, Episode 24)

"Relativity"

In a move very similar to Discovery 's "Face the Strange," this unforgettable episode of Voyager briefly takes us back to a point before the series even begins, showing us Janeway's first moments on Voyager before the ship left the Utopia Planitia Shipyards on Mars. (In "Face the Strange," Burnham and Rayner see Discovery in a drydock on Earth well before the events of Season 1.)

But, Voyager 's jaunt into its own prehistory is just the beginning of a very specific type of time jumping episode. Here, Seven of Nine isn't exactly repeating a loop, but, making several attempts at different times, to prevent a bomb from destroying Voyager . As Tuvok aptly puts it when encountering one version of Seven from the future, "Like many time paradoxes, it's improbable, but not necessarily illogical." Because this episode features multiple versions of Seven, and leaps to various eras of Voyager , it pairs very nicely with Burnham and Rayner's similar jumps in "Face the Strange." Especially the moment where Seven meets herself.

" Shattered ," Star Trek: Voyager (Season 7, Episode 11)

"Shattered"

Does Voyager have the best timey-wimey episodes in all of the Trek franchise? It's hard to say, but if there's another Trek episode that feels like an older sibling of Discovery 's "Face the Strange," it's almost certainly "Shattered," a fan-favorite episode from Voyager 's final season. Here, the captain and the first officer — Janeway and Chakotay — find themselves on a version of the ship that has been split into different time periods.

"Shattered" is one of Star Trek 's greatest retrospective episodes, touching on moments across all of Voyager 's story, and teaming past versions of characters with ones closer to the present. It's a touching story, and, structurally, it's wonderfully homaged in Discovery .

" Magic to Make the Sanest Man Go Mad ," Star Trek: Discovery (Season 1, Episode 7)

"Magic to Make the Sanest Man Go Mad"

One of Discovery 's stand-out moments from Season 1 fully set the stage for "Face the Strange" in Season 5. In "Magic to Make The Sanest Man Go Mad," Harry Mudd sets the ship on a true time loop, in which only Stamets can truly remember what is going on. Like in "Face the Strange," Stamets has a perception that exists outside of time, thanks to taking on the Tardigrade DNA in "Choose Your Pain."

This detail comes in handy in "Face the Strange," where Burnham and Stamets again have to re-team to get Discovery out of a time loop caused by nefarious enemies using time travel technology as a weapon. In Season 1, Burnham and Stamets barely knew each other, much like Burnham and Rayner's relationship in Season 5. But, if there's one thing a time loop or time-jumping episode can do, it’s make people who are just colleagues into best friends for life.

The 15 greatest Star Trek: Voyager episodes, ranked

Credit: CBS

Star Trek: Voyager was a series with a great premise and stories that somewhat frequently — but not always — lived up to it.

25 years ago today, Voyager premiered with the two-hour pilot "Caretaker" and forever changed the franchise with its introduction to the first female Captain, Kathyrn Janeway (a perfect Kate Mulgrew). Resilient, Janeway was unyielding in her efforts to get her untested crew home after they were zapped to the uncharted Delta Quadrant, 75 years away from Earth. Starfleet personnel mixing with former officers/current members of a resistance group known as the Maquis promised great, "only-on- Star-Trek " conflict — coupled with a ship stranded from the usual resources and aid afforded Kirk and Picard’s Enterprises.

Sadly, Voyager never fully embraced the full potential of that core conceit, leading Voyager to spend a big chunk of its seven-season run feeling like " Star Trek: The Next Generation lite." The ship was usually always fixed the next week if the previous one had it under attack or badly damaged. And the crew seemingly didn't mind too much about taking detours to explore and map this unknown area of space instead of doing what normal humans would — less sightseeing, more getting this 75-year journey underway as soon as possible and without distraction.

Despite Voyager 's uneven feel, when the show hit its stride, it produced some of the most entertaining hours the genre has ever seen. To celebrate Voyager 's 25th anniversary, here are the 15 best episodes.

15 . “Caretaker” (Season 1)

Voyager 's feature-length series premiere is one of the strongest pilots ever for a Trek show. Starting off at Deep Space Nine before stranding Captain Janeway and her motley crew of Maquis deserters in the Delta Quadrant, "Caretaker" has a riveting first half, peppered with exceptional character interplay. Then the pacing and tension slow in the second hour where we spend way too much time with an alien race that seems to have modeled itself after the citizens of Mayberry and The Waltons.

14 . "Eye of the Needle" (Season 1)

"Eye of the Needle" has a bittersweet twist that ranks up there with some of the best Twilight Zone endings. With the help of an anomaly via a wormhole, Voyager is able to communicate with a ship in the Alpha Quadrant. The catch? It's a Romulan vessel and not one in the same time as our lost heroes.

13 . "Dreadnaught" (Season 2)

If Speed and Runaway Train had a kid, it would be "Dreadnaught."

This compelling and tense hour of Voyager centers on engineer — the Klingon-Human Torres — struggling to reprogram a deadly missile designed by her enemy, the Cardassians, before it destroys a planet. Most of the hour is just Torres in a room, talking to a computer, and it is some of the most harrowing scenes in all of Trek history.

12 . "Mortal Coil" (Season 4)

Neelix, as a character, struggled to find solid footing among the ensemble jockeying for meaty storylines. But "Mortal Coil" remedies that with a dark, brooding storyline that takes on the afterlife and Neelix's near-death experience with it. After realizing the afterlife his culture believes in isn't really there, our favorite Talaxian suffers a heartbreaking existential crisis.

11 . "Tinker, Tailor, Doctor, Spy" (Season 6)

Veteran Star Trek: The Next Generation writer Joe Menosky — with a story from cartoonist Bill Vallely — crafted one of The Doctor's funniest outings, as the sentient hologram struggles with the hilarious consequences of giving himself the ability to daydream. The good doctor's fantasies catch the attention of an alien race's surveillance, but they think they are real — which brings about some trouble for the crew. How the Doctor saves the day is one of the best scenes Voyager has ever done.

10 . "Blink of an Eye" (Season 6) / "Relativity" (Season 5)

"Blink of an Eye" has a perfect Trek premise — Voyager orbits a planet where time passes differently for its inhabitants that for the ship's crew, so Janeway is able to watch this society evolve in, well, a blink of an eye.

This first contact scenario allows the show to invest the "explore strange new worlds" mandate with more emotion and nuance than Voyager usually affords its stories, giving fans a surprisingly poignant episode that still holds up to this day.

And despite time travel being a popular narrative trope in Star Trek , the show never failed to find new ways to explore and subvert it. "Relativity" is a fun, ticking-clock caper that sends former Borg drone Seven of Nine (Jeri Ryan) back in time to prevent the destruction of Voyager. Co-written by Discovery co-creator Bryan Fuller, this exciting episode keeps you at the edge of your couch cushion with an impressive act four twist.

09 . "The Equinox, Parts I & II" (Seasons 5 & 6)

In a plot worthy of a Star Trek movie, Janeway and her crew encounter another starship stuck in the Delta Quadrant, The Equinox. Commanded by a battle-hardened, Ahab-like figure, Captain Ransom (John Savage), The Equinox plots to hijack Voyager and strand her crew aboard their dying ship — in order to escape a race of subspace aliens that have been plaguing them.

Part of the fun of this excellent two-parter is never really knowing for most of its run time where the plot is going to go — for a moment, we actually think Janeway will lose this one.

08 . "Deadlock" (Season 2)

"Deadlock" is one of the few bright spots from Voyager 's bumpy early days. While the episode could take place on any of Trek 's ship-based shows, the stakes feel higher and for Janeway and her crew as they must work with those belonging to an alternate version of Voyager to get out of trouble.

When our Voyager — Voyager Prime — becomes fatally disabled, Janeway volunteers to sacrifice her ship so the other Voyager can go on. How Janeway handles the idea of this sacrifice results in the Ensign Harry Kim (Garret Wang) the show started with being replaced by his doppelganger.

07 . "Scorpion, Parts I & II" (Seasons 3 & 4)

"Scorpion" is action-packed Season 3 finale/Season 4 premiere that kicks off with a hell of a hook for a teaser: A small fleet of Borg cubes easily destroyed by an offscreen threat.

That threat is revealed to be Species 8472, a long-standing rival of the Borg in this quadrant of space — the only thing the Borg are afraid of. Enter Seven of Nine (Jeri Ryan), a Borg attache who becomes a remember of Janeway's crew as Voyager teams up with the enemy of their enemy to both defeat the Borg and shave some time off their trip home.

"Scorpion" represents a turning point for the series and for the franchise, with the introduction of the instantly-iconic Seven — another member of Trek’s deep bench of alien characters struggling to learn what it takes to be human. Or, in Seven's case, rediscover her humanity.

06 . "Counterpoint" (Season 5)

"Counterpoint" (Kate Mulgrew's favorite episode) is arguably Voyager 's most underrated episode, with a storyline whose elevator pitch could be "The Diary of Anne Frank" in space.

Voyager is secretly providing safe harbor to a group of telepaths being hunted by an alien race that hates them. (So, basically, Space Nazis). When the latter's charming leader defects to Voyager, and sparks a relationship with Janeway, it's instantly fraught with suspicion that boils over into bittersweet betrayal. The hour is an acting showcase for Mulgrew, as she pushes Janeway to uneasy places with the hard choices only this captain can make — and learn to live with.

05 . "Latent Image" (Season 5)

The most successful medical storylines on Star Trek are those that tap into moral/ethical dilemmas with a tech twist. In "Latent Image," the Doctor finds himself caught in the middle of both as he and Seven work to uncover who appears to have tampered with his memory — and why.

What starts as a whodunit becomes a powerful drama dealing with consent and the rights afforded all lifeforms — including artificial ones like the Doctor — when he discovers that Janeway altered his program against his will. Why? Because the doctor was confronted with a hard choice that broke him: With two patients' lives on the line, and only enough time to save one of them, the Doctor chose to save his friend.

04 . "Hope and Fear" (Season 4)

A rare non-two parter season finale, "Hope and Fear" is a landmark episode in the Janeway-Seven of Nine (Jeri Ryan) dynamic that puts the two at odds — only to come together in the end — in ways that echo Kirk and Spock.

When a sketchy alien (Ray Wise) shows up with the promise of getting Voyager home with the help of an all-too-convenient new starship, everyone fantasizes about the pros and cons of their long journey coming to an end. But the alien's plan is revealed to be a long con — he is a Borg attack survivor seeking revenge on Voyager, specifically Seven.

After he suffers a fitting but tragic end, "Hope and Fear" wraps up with a crew overcoming the letdown of still being stuck lightyears from home by focusing on a renewed purpose to keep going.

03 . "Message In a Bottle" (Season 4)

This fast-paced mix of action and comedy is a solid two-hander between Voyager’s EMH and a more advanced version (Andy Dick) aboard a sophisticated new starship that’s been hijacked (naturally) by Romulans. The two unlikely heroes are Voyager's only hope as they must use the ship's unique ability to separate into three different sections to defeat the bad guys.

Star Trek is hit and miss when it comes to comedy, but "Message In a Bottle" finds a near-perfect balance between laughs and sci-fi action while providing further proof that actor Robert Picardo is the series' MVP.

02 . "Timeless" (Season 5)

Voyager 's 100th episode is one of the greatest ever produced on any Star Trek series. "Timeless" opens in a future where Voyager crashed on an ice planet while on its way home, and centers on Ensign Harry Kim's efforts to save his crew in a very "timey wimey" fashion. (Captain Geordi La Forge, played by LeVar Burton — who directed the episode — stands in the good Ensign’s way).

With "Timeless," showrunner and writer Brannon Braga set out to do for Voyager what "The City on the Edge of Forever" did for the classic Original Series . A high bar this entertaining, high-concept hour effortlessly reaches.

01 . "Year of Hell," Parts I & II (Season 4)

Voyager achieved feature film-level quality with this epic two-parter.

Janeway and crew struggle to defeat time-manipulating genocidal villain (a perfect Kurtwood Smith) as he risks breaking the laws of physics — and chipping away our heroes' starship with battle damage — all so he can get back to his lost wife. To right that wrong, and alter the timeline by doing so, he and his time ship destroy an entire civilization. With some of the best space battles in the franchise's history, coupled with the moral and ethical dramas only Star Trek can do, "Year of Hell" is an all-timer.

30 Best Star Trek: The Next Generation Episodes Ranked

The first ever "Star Trek" spin-off, "The Next Generation," ran for seven seasons between 1987 and 1994. It defied conventional wisdom by reinventing the notion of what "Star Trek" was, introducing audiences to an entirely new ship and crew.

Living in the shadow of Kirk and Spock early on, most agree that the first two seasons disappointed , even if they showed a lot of promise (the troubled production of these initial seasons became the subject of the 2014 HBO documentary "Chaos on the Bridge"). But "The Next Generation" would become one of the best sci-fi shows ever once it found its footing and came into its own in its third year. With 178 episodes during its run, there are dozens of all-time greats, many of which just narrowly miss making this list. Episodes like "Remember Me," "The Wounded," and "Sins Of The Father" are all worthy watches, but here are the 30 that rank as the best according to IMDb.

30. Chain of Command, Pt. I

The sixth-season episode  "Chain of Command, Pt. I"  opens with Riker and the crew shocked when Starfleet removes Captain Picard from command and gives the Enterprise over to Captain Edward Jellico ("Robocop" villain Ronny Cox). But we soon learn that Picard, along with Doctor Crusher and Lieutenant Worf, is actually being sent on a covert mission inside Cardassian territory to stop a dangerous biogenic weapon, while Jellico is ordered to take the ship to the demilitarized zone to negotiate with the Cardassians. 

Even before Picard leaves, there's tension in the air. The Enterprise crew view their new captain as demanding and overbearing, while Jellico views them as soft and lazy. But though audiences may have assumed the change of command was just for a single story, the episode ends on a shocking cliffhanger that leaves the future of the entire series up in the air.

"Family"  is the direct follow-up to the beloved "Best Of Both Worlds" two-parter that saw the captain turned into the Borg villain Locutus. As part of his recovery, Picard takes a vacation to his home village in France, staying with his brother Robert and his family. The pair of siblings have a strained relationship, but Picard finally opens up to Robert about his traumatic experience with the Borg, giving fans a new insight into the soul of the Enterprise's captain.

In a B-story, Worf is visited by his human foster parents while the ship is docked above Earth. The two are concerned for Worf, who is still dealing with his exile from the Klingon Empire the previous season, and offer their support. Together, the two family-related plots form the backbone of an episode with no space action or alien contact, but with drama that is much more poignant and personal.

28. Reunion

"Reunion"  features the return of Lieutenant Worf's lover K'Ehleyr, previously seen hooking up with the Enterprise's Klingon security officer in Season 2. This time, she comes aboard with news of an impending Klingon war, and has come at the request of Chancellor K'mpec, who is on his deathbed. After he dies, he needs Picard to ferret out the man who poisoned him: one of the two men vying for the leadership of the Empire. Newcomer Gowron is one suspect, but the other is Duras, who had framed Worf's father to cover up his own family's dishonor in the Season 3 episode "Sins Of The Father."

When K'ehleyr arrives, however, she also brings a surprise: Alexander, the child she bore with Worf two seasons earlier. An important episode that changes the lives of several characters and introduces the fan-favorite Gowron , "Reunion" is also a key piece of the story of Worf's family honor that would continue throughout "The Next Generation" and into "Deep Space Nine" — his son Alexander would become a recurring character in both series.

27. The Drumhead

Retired and revered Rear Admiral Norah Satie comes to investigate the Enterprise in  "The Drumhead"  when there appears to be a saboteur onboard. After a rogue Klingon exchange officer is caught stealing information, the case is seemingly closed, but when the warp core is damaged in an apparent act of sabotage, Satie comes to believe there are others involved. What follows is a dark tale that sees the admiral peeling back layers of what she thinks is a vast conspiracy.

But after exposing a young officer who lied about his heritage to get into Starfleet, Satie threatens to drag everyone into her web of suspicion, even Captain Picard. "The Drumhead" is a fascinating look at paranoia and how fear can be used to subvert democracy, spreading like a disease, all in the name of freedom and liberty. It's a cautionary tale, and one of "Star Trek's" most timeless political parables.

26. The Next Phase

"The Next Phase"  adds a new stunning piece of advanced technology to "Star Trek" lore when the Enterprise comes to the aid of a disabled Romulan ship experimenting with a "phasing cloak." When the ship's transporter mixes up LaForge and Ensign Ro, the pair become trapped in a kind of limbo, cloaked and phased so they can pass through ordinary matter. Unable to communicate with anyone else aboard the Enterprise, the situation escalates when they overhear the Romulan commander tell his crew to rig the ship so that the Enterprise will be destroyed when they activate their warp drive.

With the clock ticking, Geordi and Ro must find a way to warn their shipmates and return to their normal state, all while being pursued by a Romulan who they find trapped out of phase with them. Fast, fun, and exciting, "The Next Phase" is one of the series' most thrilling adventures.

25. Time's Arrow Pt. I

The fifth-season cliffhanger finale  "Time's Arrow"  opens with archaeologists uncovering Data's head buried beneath San Francisco. Realizing the discovery means that at some point in the future Data will be hurled back in time to the 19th century, where he will die, Picard attempts to keep Data safe from this lethal destiny. But when an unusual signal leads the Enterprise to discover an alien race who is traveling into the past and murdering humans in 1893 to absorb their life force, the Captain realizes it may simply be Data's fate to die in the past. 

Sent back in time, Data allies himself with the 19th-century version of the Enterprise's bartender, Guinan, who turns out to be far older than anyone ever realized. At the same time, he's also brought to the attention of Mark Twain, who will become an unexpected adversary in the second half of the two-part adventure. Though not the most bombastic of episodes, it proves its worth as a classic "Trek" time travel story.

24. Unification Pt. II

After the reveal that Leonard Nimoy would be returning as Mr. Spock in the Season 5 two-parter "Unification," some fans were left disappointed when his appearance in the first part was limited to a single scene in the closing moments. But he takes center stage in  "Unification, Pt. II,"  which sees Spock on Romulus after apparently defecting from the Federation. Picard and Data — disguised as Romulans themselves — find that Spock is working with an underground sect that wants to reunify the Romulans with their Vulcan cousins.

The episode also featured the unexpected return of the  Romulan villain Commander Sela  and includes some classic moments between Spock and the "Next Generation" crew, particularly Data. Picard and Spock, meanwhile, share some of the most important and thoughtful interactions in all of the series, and in his final television performance as his Vulcan character, Nimoy delivers a momentous performance.

23. Redemption, Pt. II

Season 5 opener  "Redemption, Pt. II"  concluded the cliffhanger from the fourth-season finale, revealing the mastermind behind the Romulan alliance with the Klingon Duras family to be Commander Sela, who claims to be the daughter of long-dead Enterprise security chief Tasha Yar. As the two Klingon factions — led by Chancellor Gowron and the Duras sisters — duke it out for the fate of the Empire, Worf resigns his commission and joins the fight. Picard and the Enterprise had previously vowed to remain neutral, but now devise a plan to expose Romulan involvement.

The plan, involving a fleet of Federation starships forming a blockade around the Neutral Zone, puts Data in the captain's chair of the USS Sutherland, where he must contend with the bigoted Lieutenant Hobson. An episode filled with drama, it gives both Worf and Data some of their best, most satisfying moments in the series.

22. Redemption, Pt. I

"Redemption, Pt. I,"  the Season 4 finale, opens with Gowron requesting that Captain Picard see through his commitment to help install him as the new Klingon Chancellor. But a challenger appears in the form of a young warrior named Toral, brought forward by the Duras sisters, who themselves are the surviving kin to the man Worf killed in combat in "Reunion." Known traitors, the House of Duras cannot be trusted, but Picard — as the Klingon Arbiter of Succession — is duty-bound to consider their claim.

When Toral is dismissed as possible leader of the Empire, a Klingon civil war begins. But all is not as it seems — Worf suspects that the Duras sisters are getting help from the Romulans, and leaves Starfleet to aid in Gowron's fight against them. Full of twists and turns, it doesn't quite match the legendary Season 3 finale, but it comes close.

21. The Defector

"The Defector"  is classic "Trek" — a gripping political drama, the story of an enemy soldier who defects to the Federation, risking his life to help avert a war. Claiming to be a low-level logistics clerk, a Romulan officer named Setal insists that his people are readying for an all-out invasion, and he has deserted his homeworld to warn the Federation. Picard is skeptical, as to prove Setal's claims, the Enterprise must enter the Neutral Zone in violation of the Federation's treaty with the Romulan Empire, and at the risk of starting a war.

Stuck in this quandary, Picard and his crew must decide whether Setal is telling the truth and truly trying to help, or is in fact attempting to bait him into being an aggressor. With the stakes so high, "The Defector" is a tension-filled episode that ends in a dramatic and surprising conclusion — particularly when Setal's true identity is revealed.

20. The Offspring

An important and sometimes overlooked episode, the "The Offspring"  sees Commander Data create his own android child named Lal. Choosing her own appearance and gender identity, Lal becomes a young human woman with a naive but wide-eyed and wondrous outlook and personality. But things take a dark turn when a Starfleet admiral arrives to take Lal away, claiming that the creation of a new android life needs to be carefully overseen by Federation experts. Torn between loyalty to Data and his duty to Starfleet, Picard once again finds himself fighting for the rights of androids to make their own choices. 

A quasi-sequel to the iconic Season 2 episode "The Measure of A Man" but overshadowed by bigger episodes that sandwiched it, "The Offspring" is an intimate character piece with a classic moral dilemma and an emotional ending, and received renewed attention thanks to its importance to the plot of the first season of "Star Trek: Picard."

19. The Pegasus

Season 7's  "The Pegasus"  begins with the arrival of Admiral Erik Pressman, who happens to be Riker's old captain from the titular starship Pegasus. He comes with new orders for Picard, telling him that the Pegasus wasn't destroyed as had been previously believed, and has been found buried in an asteroid field ... and the Romulans are after it.

It's soon revealed that the Pegasus was once used to test an experimental Federation cloaking device, an act specifically prohibited in the treaty with the Romulans. Commander Riker's loyalty is questioned when he is ordered to keep the secret of the Pegasus, and he's forced to choose between his two captains when the Enterprise falls into a Romulan trap. "Lost" star Terry O'Quinn makes a memorable appearance as Pressman, while Picard and Riker get into some heated exchanges about mortality and integrity that make "The Pegasus" a nail-biter of an episode.

The only pure comedy episode on this list,  "Deja Q"  earns its place as one of the best episodes of "The Next Generation" thanks to the sharp wit and strong performance of John De Lancie, who returns once again to serve as a thorn in Picard's side. As the immortal trickster Q, he arrives on the Enterprise claiming he has lost his god-like powers and has been exiled from his people in the Q Continuum. He asks for a safe haven aboard Picard's ship, which becomes a cry for help when a race of beings shows up to get vengeance on him for tormenting them in the past.

Most of the humor of the episode comes from Q slowly learning the basics of being mortal, from nightly sleep to being hungry to crippling back pain. But "Deja Q" also includes many touching moments involving Data, who somewhat ironically attempts to show Q what it means to be human.

After featuring Spock the previous season, Season 6 dips back into the original "Star Trek" series lore with  "Relics," the episode that brings back Enterprise-A chief engineer Montgomery Scott. Having apparently survived for 75 years by storing himself within his ship's transporter, "Scotty" re-materializes aboard the Enterprise-D during an investigation of a fantastic alien Dyson Sphere and is warmly greeted, but soon begins to feel out of place in the 24th century. When the Enterprise gets trapped inside the Dyson Sphere, it's up to Scotty and his engineering successor, Geordi LaForge, to save them.

Ultimately, the return of Scotty is a touching story about aging and the need to feel useful in an ever-changing world. While the genius former engineer feels that the future has left him behind, he soon discovers that he still has plenty of life left in him, and a lot to offer the 24th century.

16. Ship In A Bottle

A sequel to one of the better Season 2 episodes, the Season 6 follow-up  "Ship In A Bottle"  ties up what might have wound up an unresolved plotline . It begins when a self-aware hologram of Professor James Moriarty — Sherlock Holmes' ultimate nemesis in the stories by Arthur Conan Doyle — appears on the holodeck demanding to see Captain Picard. After Data and Geordi unwittingly gave him sentience in "Elementary, Dear Data," Moriarty's program has been trapped in the holodeck computer for years, and now he wants to leave. But as far as Picard and crew believe, it's simply not scientifically possible.

But Moriarty has a plan and takes control of the ship, threatening to destroy it if his demands aren't met. What follows is a mind-bending "Inception"-style adventure where Moriarity and Picard — with the help of Data and the neurotic recurring character Reginald Barclay — attempt to trick each other with dueling holodeck-within-a-holodeck scenarios that will leave your head spinning.

15. Timescape

Stories that play with time have been a staple of "Star Trek" since the beginning, and time-bending episodes are often among the franchise's best.  "Timescape"  is no exception. Returning to the Enterprise from a science conference, Picard, Geordi, Data, and Troi discover the Enterprise and a Romulan warbird frozen in time, seemingly in the midst of battle. Going aboard, they find the crews frozen, as well — both ships are trapped in a strange anomaly, and any attempt to unfreeze them in time risks killing several members of the Enterprise crew, who are apparently under attack by Romulan soldiers.

When Picard becomes incapacitated, the remaining trio must figure out what's really happening, despite interference from mysterious pair of Romulans who, like them, are able to move freely about the Enterprise. With loads of fun, sci-fi time-altering shenanigans, and its far share of twists, "Timescape" is an episode full of surprises.

Among the most famous episodes of the series,  "Darmok"  may not rank in the top 10, but it comes close. The story sees Captain Picard kidnapped and brought to the surface of an unknown planet along with a ship captain from a species known as the Children of Tama, whose language has proven indecipherable despite the Federation's universal translator technology. Trapped together on the alien world and forced to work together to fight a deadly beast, Picard and his fellow captain find common ground and slowly learn to communicate.

The unusual language structure devised for the episode proved groundbreaking — it's been pointed out that the Tamarian "language" predicted Internet meme culture , and it's even been used to teach college courses . The uniqueness of this language is one of those fascinating concepts that could only be seen in science fiction, and the episode as a whole is quintessentially "Star Trek," with a universal message of friendship, tolerance, and understanding.

13. I, Borg

The compassion of Captain Picard and the crew of the Enterprise is on full display in the Season 5 episode  "I, Borg."  Coming upon the wreckage of a Borg ship, Doctor Crusher convinces the captain to bring the last surviving drone aboard to save his life. But while Picard's intentions are initially less selfless — he hopes to use the drone to destroy the entire collective — he comes around when he realizes that this new Borg is showing signs of personhood, even taking the name Hugh.

An example of the moral and ethical dilemmas often faced in "Star Trek," Picard ultimately abandons his plans for revenge against the Borg and allows Hugh to decide his own fate. Realizing the Borg won't stop looking for him, Hugh returns to the Collective, with the hope being that his sense of individuality will survive and spread. It proves to be one of Picard's best decisions  — Hugh would return later in "The Next Generation," and again in the first season of "Star Trek: Picard."

12. Lower Decks

The story that inspired the modern adult animated comedy of the same name,  "Lower Decks"  was a unique episode of "The Next Generation" that focused on a group of younger officers: Nurse Alyssa Ogawa, Ensign Sam Lavelle, the Vulcan Ensign Taurik, and the Bajoran Ensign Sito Jaxa, who had previously been seen getting into trouble at Starfleet Academy in the Season 5 episode "The First Duty." Now, the young officers are all up for promotions, and as their friendship is tested by their career ambitions, we see the struggles, challenges, and everyday life of the lower-ranking officers serving on the Enterprise.

Meanwhile, Jaxa is confronted by Picard about her troubled past, a prelude to her assignment to a dangerous mission to return a Cardassian defector to his people. A generally upbeat story, "Lower Decks" is a fun detour from the senior bridge crew, but it ends on a surprisingly bittersweet note.

11. Chain Of Command, Pt. II

A darker episode than most on this list,  "Chain Of Command, Pt. II"  concludes a two-part episode that saw Picard kidnapped by the Cardassians on a mission to stop a rumored doomsday weapon. At the mercy of a cunning Cardassian named Gul Madred, he resists and becomes the subject of brutal psychological torture. Over the course of the episode, it becomes clear that while Madred definitely wants to acquire Federation secrets, the thing he wants most of all is to break Picard's spirit.

Meanwhile, on the Enterprise, Jellico is clashing with Commander Riker, who feels his new captain is too controlling. But Riker may also be the only man who can execute Jellico's daring plan to expose the Cardassian plot and save Captain Picard. Picard's defiant shout of "There are four lights!" puts an iconic capper on one of the better late-series episodes.

10. Parallels

Years before Marvel's "Loki," the "Next Generation" Season 7 episode  "Parallels"  put the multiverse front and center when Worf inadvertently passes through a split in the barriers between universes. Moving between them throughout the episode, Worf finds himself in new and different realities: some where Riker is captain, some where he is married to Counselor Troi, and some where the Bajorans are the Federation's greatest enemy. 

Another trippy sci-fi story, most of the fun is in the first half as Worf struggles to figure out what's happening to the world around him as events and people change before his eyes, though the episode also features a daringly ambitious climax. The various windows into what might have been are intriguing, and "Parallels" even takes the opportunity to bring back Wil Wheaton as Wesley Crusher. It also introduces the first spark of romance between Worf and Troi, a sub-plot that would continue through the remainder of the show's final season. 

9. Tapestry

Q has traditionally been a major pain for Picard and other Starfleet captains, but he returns in  "Tapestry"  in the surprising role of benevolent spiritual advisor. Picard is actually killed in the opening moments of the episode, only to greeted by the all-powerful trickster in the apparent afterlife, who offers Picard a chance to relive his past and change moments that he regrets.

Returning to his days as an ensign fresh out of the Academy, Picard hopes to avoid the reckless behavior that got him stabbed through the heart in a bar fight as a young man while also pursuing a romance with one-time friend Marta Batanides. In trying to bring his older wisdom to his younger self, however, he learns that life's mistakes help us to become who we are. A "Star Trek" version of "A Christmas Carol," the heartwarming message of "Tapestry" makes it one of the series' best.

8. All Good Things...

Often voted among  television's best series finales ,  "All Good Things..."  capped off the show's remarkable seven-year run with an epic feature-length episode that saw Picard revisit events in both the future and the past. Harkening back to the series' very first episode, "Encounter at Farpoint," we see Picard once again on trial before the Q Continuum, attempting to prove the value of humanity's existence by piecing together clues to a potentially world-ending mystery in three different time periods.

As Picard struggles to convince three different crews that what's happening is real, he must find answers to a puzzle that stretches back to the dawn of time to save his entire species. Full of drama, action, and emotion, it was just about everything a fan could want in a finale. While the episode would be one of the series' best on its own, it works even better as a final bookend to "The Next Generation."

7. Cause and Effect

  "Cause and Effect"  is a near-perfect science fiction riddle. Opening in the middle of the action, the Enterprise is destroyed in a shocking scene before the opening credits even roll. Coming back from the iconic "Star Trek" music and fanfare, we find the crew is trapped in an endless loop of time that inevitably leads to the ship's destruction, and worse — they have no idea it's happening. Thinking each loop is the first time through, the crew struggles to even realize what's going on, let alone collect the clues to figure out how to stop it before they all blow up yet again.

With the destruction of the Enterprise occurring just before each commercial break, it's a maddening but mind-blowing story that will leave you on the edge of your seat until the very last moments. And don't forget to keep your eyes peeled for a memorable cameo from Frasier himself, Kelsey Grammer.

The fourth episode to feature Q on this list, Season 2 entry  "Q Who"  saw the more sinister aspect of the god-like being, who arrives on the Enterprise and asks to join the crew. Picard, of course, turns him down. Incensed and hoping to prove to Picard that humanity is not ready for what awaits them amongst the stars, Q flings the ship into a distant uncharted region of space. There they encounter, for the first time, the mysterious race of cybernetic beings known as the Borg. They also learn that Ten Forward bartender Guinan is already familiar with the hostile hive mind, which annihilated her home world.

An important episode in the series, and "Star Trek" as a whole, it's also one of the best — a well-paced thriller that has Picard at first hoping to prove Q wrong and attempting to make peace with the Borg, but ending with an ominous warning that foreshadows not one but two of our remaining entries.

5. The Measure Of A Man

A landmark episode that has been analyzed by  legal scholars , Season 2 standout  "The Measure Of A Man"  puts android Commander Data in the spotlight when a brilliant cyberneticist named Bruce Maddox arrives and wants to disassemble him so he can recreate his positronic brain. Data doesn't approve of the risky procedure, but Maddox states that Data is the property of Starfleet and cannot decline. Picard fights back against this notion and demands a hearing so that he can defend Data's rights. However, the hearing takes place at a poorly-staffed starbase, and Commander Riker is forced to act as prosecutor against Data, despite his personal feelings for his fellow officer.

One of the franchise's best examination of ethics and human rights, it's also one of its most important, as "The Measure of a Man" explores issues that would be revisited again in many future episodes, both in "The Next Generation" and other "Trek" spin-off series. Maddox would even return in the first season of "Star Trek: Picard" in a quasi-sequel that explores the fallout from the work of Noonian Soong, Data's creator.

4. Yesterday's Enterprise

"Yesterday's Enterprise" takes place in a darker alternate timeline created when the Enterprise-C, predecessor to the ship captained by Picard, finds itself thrust 22 years forward in time. Without its sacrifice at a crucial moment in the past, all of history was altered, and now Picard's Enterprise is a warship, with the Federation engaged in a bitter conflict with the Klingons — and on the verge of defeat.

But the arrival of the Enterprise-C adds new complications to an impending Klingon attack, and when Picard learns that the war was never supposed to happen, he struggles with the decision to send it and its crew back to their proper time to face certain death. The episode that saw the return of long-departed cast member Denise Crosby as Tasha Yar, it's an important piece of "Next Generation" lore, and possibly the best alternate reality episode in the entire franchise. 

3. The Best Of Both Worlds, Pt. II

Opening up Season 4,  "The Best Of Both Worlds, Pt. II"  is the thrilling second part of  one of television history's best cliffhangers . The previous episode had ended with Commander Riker giving the order to open fire on the Borg cube that held Locutus — the assimilated Borg drone that had once been Captain Picard. Audiences who had waited all summer for the attack tuned in to see the cube survive unharmed, and Riker and the Enterprise helpless as the Borg launch a direct assault on Earth.

After Starfleet loses a devastating battle with the Borg at Wolf 359, it's up to Riker to devise a bold last-ditch plan to rescue Picard and save Earth from assimilation. The series' most gripping season conclusion, it's an episode that "Star Trek" has still never been able to match in terms of sheer anticipation and excitement.

2. The Best Of Both Worlds, Pt. I

As a stunning season finale and the first cliff-hanger of the franchise, "The Best Of Both Worlds, Pt. 1"  could rightfully be credited as the episode that turned "The Next Generation" into a genuine pop culture phenomenon. Discovering a Federation colony decimated in the same manner as the alien civilization they found destroyed by the Borg in "Q Who," Picard alerts Starfleet that a confrontation may be near. Admiral Hanson arrives with a new officer, Lieutenant Commander Shelby, to help with the crisis. 

The ambitious Shelby adds an interesting layer in what turns out to be a Riker-focused episode, as the title refers to Riker's struggles with whether to leave the Enterprise to become a captain of a lesser ship, or stay and remain Picard's first officer. When his captain is abducted by the Borg and declared lost, Riker gets the best of both worlds — at the cost of Jean-Luc Picard.

1. The Inner Light

"The Inner Light" isn't just the best "Next Generation" episode — there's an argument to be made that it's the best "Star Trek" episode, period . The story begins when the Enterprise comes upon an alien probe that zaps Picard unconscious right off the bat. The captain awakens on an alien world, in another life. Here on the planet Kataan, in the community called Ressik, Picard is a man named Kamin, with a wife named Eline. After giving up on ever finding the Enterprise, which seems to have been just a dream, Picard settles into his new life, even having children and grandchildren, all while Kataan is slowly dying of drought.

Now an old man nearing death, Picard learns that the probe was a messenger that carried memories of a long-dead civilization, and wakes up on the Enterprise having experienced an entire lifetime over the course of a few minutes. An example of what made "The Next Generation" so special, the episode's message of love, hope, and family help it remain one of the most beloved pieces of television ever conceived.

Star Trek: Discovery Season 5 Episode 6

Star Trek: Discovery (mostly) gets its final season back on track after last week’s flashback-filled snoozefest , but Michael and company’s search for the next clue hits a snag when the trail leads to a pre-Warp planet whose lack of technology makes accessing it more of a challenge than anyone expected. It’s a shift that comes as a welcome relief—the best part of this more adventure-oriented season has been its old-fashioned space explorer feel as Burnham and her crew bounce from planet to planet (or random interdimensional pocket of space). And it’s nice to finally get back to that, even if the planet Halem’no isn’t quite as exciting a side quest as some of us (read: me) may have wanted it to be.

The planet is largely arid, with a habitable zone that’s been created thanks to the work of Denobulan scientist Hitoroshi Kreel. A weather tower disguised as a sort of mountain peak, the tech emits a low-grade force field that protects the land around it from dust storms and pulls rain from the atmosphere on a semi-regular basis. All in all, it’s a technology that’s wildly advanced for the pre-Warp, pre-industrial society that lives on its surface and may have been built as part of some kind of humanitarian mission to help the people on its surface survive. The question of how, precisely, Kreel managed to do this without anyone on the planet noticing or why he chose this particular spot to hide his clue is something the episode is happy to handwave away. But, sure! Why not!

But, then again, very little about this consortium of old scientists determined to hide the Progenitor technology makes a ton of sense. Thanks to Kovich, we at least learn the identities of all five participants—Jinaal Bix (Trill), Carmen Cho (Terran), Marina Derex (Betazoid), Hitoroshi Kreel (Denobulan), and Vellek (Romulan)—who each came up with their hiding places and clue themes tied to their own lives or areas of expertise. ​How they all joined forces is anyone’s guess, but at least we have something of a roadmap as to where we’re headed now. (And I have to assume the Betazoid scientist is named in honor of Star Trek: The Next Generation ’s Marina Sirtis, which I admittedly already love.)

After Tilly and Michael disguise themselves in shabby, planet-appropriate attire (complete with convenient retinal tricorders that only make them look a bit like they belong in The Matrix ), they beam to the surface of Halem’no, which—at least in its habitable zone—is lush and green. The conceptualization of this planet and its society is the most intriguing part of this episode—particularly the phonetic elements of their language, known as Whistlespeak, which sounds like birdcall, doesn’t have words to denote things like class or status, recognizes at least three distinct genders, and prioritizes connection amongst its people. A timely reminder that simply because a society is not advanced in one way, doesn’t mean it isn’t in another. 

To find the next clue, Team Discovery must make their way inside the High Summit, the weather tower that the locals see as a place to commune with their gods and pray for the rain that keeps them all alive. A sacred place, access is restricted to those deemed especially holy or chosen through a race called the Journey of the Mother Compeer. Michael and Tilly immediately decide to participate in this very specific ritual without doing any research in it or even asking around about why everyone who’s won it appears to no longer be alive. To the surprise of no one, it’s actually a method of choosing those who will be sacrificed within the tower, trading their lives for the promise of rain and the chance to commune with their gods before they die. Tilly wins, because of course she does, and she allows a kind young woman named Ravah to tie with her so that she can too fulfill her dream of proving herself to her father, and now they’re both essentially marked for death. Good times! 

Not that any of us likely really expected Tilly to suffocate during this episode or anything, but truly the speed with which Michael jettisons the Prime Directive in the name of saving her friend is…honestly, something I wish the show would explore in a bit more depth. Because it actually ought to be an interesting story about how important Tilly is to her! Instead, it’s…just another example of the way that Michael’s constantly allowed to break the rules in ways that others are repeatedly punished for. Because, let’s face it, Rayner was demoted and publicly humiliated for doing much less.

And, for whatever reason, Discovery feels the need to overtly justify Michael’s choice, deliberately leaning into the idea that because she’s in for a penny, she might as well be in for a pound. I mean, it’s one thing to explain that the High Summit is a weather machine rather than the seat of vengeful gods. But it’s quite another to literally ferry Ravah’s dad Ohvanz up to their actual spaceship that is parked in space and show him what his planet looks like from orbit! Did she leave a spare warp drive behind her to top everything off? Maybe it all would be less annoying if it had truly ever felt as though Tilly was in some kind of real danger, or if it seemed as though the show was finally ready to tackle the cost of Michael’s reckless choices in a more serious and lasting way. Instead, it’s just another convenient shortcut she’ll inevitably face no consequences for. 

If every one of these clue hunts is supposed to either teach or test the person doing the searching—to ensure they’re trying to find the Progenitor technology for a good reason—what is this search (and Michael’s response to it) meant to show us? That friendship is magic? That climate change is real? That false gods exist? That you shouldn’t allow your loved ones to participate in poorly explained and potentially deadly rituals? Or it’s okay to do whatever it takes to save someone you care about, even if it means breaking rules to do so?

It’s particularly jarring when much of this episode is about unintended consequences—about what can happen when technology is used irresponsibly, even with the best intentions of the world behind it. The Denobulan scientist Hitoroshi Kreel tried to do a good thing by disguising high-tech weather equipment in what is essentially religious iconography, but it still ended up giving rise to ritual sacrifice and murder in the name of bringing rain. Discovery isn’t normally very subtle about such parallels, so I think we can all assume that whatever the Progenitors did leave behind for future generations to find, the question for Michael and the Federation will be more about whether anyone should have access to it at all. 

With just one more clue to go—and four more episodes in the season—-it’s anyone’s guess what’s coming as the Discovery enters the final phase of this story. Will Michael manage to unearth the Progenitors’ ancient, potentially galaxy-changing secret? Or will it turn out that the real advanced technology was actually the friends we made along the way?

• The dedication plaque on the starship sheds light on events in the late-23rd century after "Mirror, Mirror" from TOS season 2.
• Burnham and Booker found the ISS Enterprise in interdimensional space and brought it into the 32nd century Prime Universe.

Star Trek: Discovery season 5, episode 5, "Mirrors", shockingly brought the ISS Enterprise into the 32nd century, and the starship's dedication plaque reveals new details about the Mirror Universe's history. Written by Johanna Lee and Carlos Cisco and directed by Jen McGowan, "Mirrors" brought Captain Michael Burnham (Sonequa Martin-Green) and Cleveland Booker (David Ajala) into interdimensional space in pursuit of the next clue to the ancient treasure of the Progenitors, which was hidden aboard the 23rd century ISS Enterprise from the Mirror Universe.

On his X account, Jörg Hillebrand (@gaghyogi49), who was a researcher for Star Trek: Picard season 3 renowned for his attention to detail, posted a clear translation of the ISS Enterprise's dedication plaque from Star Trek: Discovery season 5, episode 5 . The illuminated text reveals what happened in the late-23rd century Mirror Universe after the events of Star Trek: The Original Series season 2's "Mirror, Mirror." Read the post below:

Star Trek: Discovery Season 5 Returning Cast & New Character Guide

A timeline of star trek's mirror universe, from the terran empire to the temporal wars.

The Mirror Universe was introduced in Star Trek: The Original Series season 2's "Mirror, Mirror" and its canonical history can be tracked through Star Trek: Deep Space Nine, Star Trek: Enterprise, and Star Trek: Discovery. The earliest chronological glimpse of the Mirror Universe is on April 5, 2063, when Zephram Cochrane (James Cromwell) murdered a Vulcan after making First Contact in Enterprise 's "In A Mirror, Darkly". In the 22nd century of Star Trek: Enterprise 's Mirror Universe , Commander Jonathan Archer (Scott Bakula) captured the USS Defiant from the 23rd century, but he was betrayed by Hoshi Sato (Linda Park), who declared herself Empress of the Terran Empire.

In the 23rd century of Star Trek: Discovery , the Mirror Universe was ruled by Emperor Philippa Georgiou (Michelle Yeoh). Georgiou jumped to Star Trek 's Prime Universe aboard the USS Discovery after defeating a coup by Gabriel Lorca (Jason Issacs) . The Terran Empire continued unabated, but after Captain James T. Kirk (William Shatner) briefly switched places with his Mirror Universe counterpart, he convinced the Mirror Spock (Leonard Nimoy) to institute reforms to save the Terran Empire from its inevitable collapse.

Refugees fled the Mirror Universe aboard the stolen ISS Enterprise.

Star Trek: Discovery season 5 episode 5 reveals that High Chancellor Spock did change the Terran Empire, but he was assassinated for weakness. Refugees fled the Mirror Universe aboard the stolen ISS Enterprise, thanks to the Mirror Saru (Doug Jones), a rebel leader. The ISS Enterprise's personnel did make it to the Prime Universe. However, in the Mirror Universe, the Terran Empire was conquered by the Klingon/Cardassian Alliance , as detailed in Star Trek: Deep Space Nine . By Star Trek: Discovery 's 32nd century, the Mirror and Prime Universe timelines have split further apart thanks to the Temporal Wars, making crossing over impossible.
