5 Brilliant Star Trek Episodes That Feel Like a Whole Movie

Many have claimed that while Star Wars is for the big screen, Star Trek works best on TV. They are not completely wrong. The sci-fi franchise works best as a slow-burning exploration of the human condition rather than bringing down a Galactic Empire. But just as The Mandalorian was a hit on streaming, some Star Trek episodes prove why it can be cinematic.

Across multiple shows, the Star Trek franchise has given complete stories that feel like an arc has been explored. It satisfies emotionally, in terms of scale, and gives closure to the key question for the character being portrayed. Here are five episodes from the franchise that feel like a whole movie. 

1 The City on the Edge of Forever – Star Trek: TOS

The Original Series was highly ambitious, with Gene Roddenberry’s vision being clear on what the show was supposed to explore. The season 1 episode ‘The City on the Edge of Forever’ pioneered complex temporal mechanics and alternative timelines long before they became a mainstream trope, and explored the underlying loneliness in being a Starfleet captain.

The episode sees Captain Kirk travel back to Depression-era New York, where the captain falls in love with a social worker. Tragically, he learns that through a devastating butterfly effect, her survival will cause a massive pacifist movement that delays the United States’ entry into World War II, allowing Nazi Germany to conquer the world. It is a tragic story that shows a complete arc for Kirk before punching our guts with a twist. The period setting adds to the scale of the show, making it seem blockbuster-like.

2 The Inner Light – TNG

Another episode where a captain’s inner hopes and dreams, and the wish for companionship, are explored. The TNG episode, ‘The Inner Light,’ begins when Captain Jean-Luc Picard is struck unconscious by a beam from an ancient, mysterious alien probe… Picard experiences forty years of a lifetime inside his mind as Kamin. He becomes Kamin, a resident of the non-Federation planet Kataan.

While the Enterprise crew tries to retrieve their captain, Kamin/Picard enjoys a life that is fulfilling and ideal. With his wife and children, Picard gets a whiff of what an alternative life could be, and he gets a tragic awakening at the end.

‘The Inner Light’ is a complete story, spanning decades in the subconscious, and adds a beautiful edge to Picard’s character. It is also Sir Patrick Stewart’s favorite episode on the show.

3 In the Pale Moonlight – Deep Space Nine

Deep Space Nine explored several facets of the Star Trek universe that had not been seen before on screen. Unlike other shows, DS9 was stationed at a singular place and also featured the Dominion War as the primary storyline (instead of an episodic structure). In the season 6 episode, ‘In the Pale Moonlight’, the war reaches its peak.

The episode is told in flashback format, with Captain Sisko narrating through a personal log. It sees him work with a spy, Garak, to forge evidence that the Dominion is attacking the Romulans to convince them to join the Federation in war. It is one of the most devastating things that a Star Trek captain has done, and the arc of Sisko deciding to do it is a complete one.

Sisko’s morally grey act, the ambition of an espionage happening, and the sheer desperation of a losing war create a masterfully tense psychological thriller. Still, the scale and ambition in terms of character journey is what makes it movie-like.

4 Scorpion (Parts I and II) – Voyager

A two-parter may be a cop-out in this list, but what matters is the storyline being episodic and airing on TV (it is my list, I make the rules). The Voyager episode, ‘Scorpion,’ followed the cliffhanger format used by TNG with ‘The Best of Both Worlds.’ Similarly, the show introduced a ruthless villain in the form of Species 8472.

The threat of a monstrous species, the prospect of going to war with them, and an intense conversation about how to navigate this predicament make this episode full of tension and suspense. The tension of navigating a truce with the galaxy’s most dangerous cybernetic threat makes the episode crackle with suspense, perfectly setting up a cinematic shift for the rest of the series by introducing Seven of Nine.

5 Azati Prime – Enterprise

Star Trek: Enterprise is not the best show in the franchise (far from it), but season 3 was genuinely so good. The Xindi arc is one of the best storylines in the franchise, and the show gave it the treatment it deserved. If only the show had enough eyes and vision to push it till season 7 like the rest of the Star Trek entries.

The season 3 episode, ‘Azati Prime,’ is the beginning of the end of the Xindi War, taking the threat to the maximum before all hell breaks loose in the subsequent episodes, ‘Damage’, and ‘The Forgotten’. It sees Captain Archer ready to sacrifice himself and sees the death of multiple crew members. It can be seen as the first movie of a planned trilogy, taking the ambition to the next level.

Bonus: Year of Hell (Parts I and II) – Voyager

Here is a bonus two-parter, again from Voyager. This is Star Trek at its best, exploring temporal situations, metaphysical consequences, and political undertones. ‘Year of Hell’ features Kurtwood Smith as Annorax, a Krenim scientist who is hoping to rewrite history by changing the timeline. The Krenims are holding the Voyager hostage.

It is a two-parter, with Annorax being the primary antagonist. But you empathize with the man as he attempts to save his world and bring back his wife (who died because of his own actions). It is tragic, it is ambitious, and it has a cinematic conclusion. Star Trek gets the best out of some actors through sheer writing alone.
