* AccidentalInnuendo: In "This Side of Paradise", Kirk says of Spock "[[HoYay Aroused, his]] [[IsThatWhatTheyreCallingItNow great physical strength]] [[HoYay could kill.]]"
* AmericansHateTingle: Many international fans dislike "The Omega Glory", thinking it indulges too much in {{Eagleland}}. [[BrokenBase Not that there aren't a significant number of Americans who share the exact same view...]]
* AngstWhatAngst: In "Operation -- Annihilate!", the jocular tone of the epilogue is somewhat jarring, considering the deaths of Kirk's brother and sister-in-law are not even mentioned. (A more sombre scene that would have immediately preceded it and wrapped up that subplot was filmed but cut for time.)
* BestKnownForTheFanservice:
** "The Menagerie": The green slave girl.
** "The Naked Time": A shirtless ''and freaking ripped as hell'' Mr. Sulu. Oh my!
** "Mirror, Mirror": Shatner's guns and Nichols' abs of steel.
** Hell, practically every female on the show. Roddenberry included women more out of a sense of decoration than equality, and he liked'em with big doe eyes and bigger boobs. [[http://www.vice.com/read/off-hollywood-denise-crosby This]] interview by Denise Crosby (who played Tasha Yar over on ''Series/StarTrekTheNextGeneration'') reveals that he more or less told her that this was her sole purpose on the show, which is one of the reasons that led her to resign. Apparently most of the feminism in the show came from the writers rather than Gene.
* CanonFodder: The Romulan War, and in particular Stiles' ancestor's role in it, as mentioned but not elaborated on in "Balance of Terror".
* CargoShip:
** Kirk and the ''Enterprise'', the only lady he truly loves. Made hilarious by one episode in which the ship's computer is programmed to call him "dear".
** Hell, in "Elaan of Troyius" Kirk is able to single-handedly overcome a love potion just because he loved the Enterprise so much!
** And Scotty/Enterprise.
-->"Don't you think you should...rephrase that?"
* CompleteMonster: Melakon from season 2’s “[[Recap/StarTrekS2E21PatternsOfForce Patterns of Force]]” was a devotee of Nazism introduced to his people in an attempt to soften it by a former Starfleet officer named John Gill. Shunning the attempt to water down Hitler's philosophy, Melakon decided to embrace Hitler's path. He overthrew his mentor and formed a fascist regime on his homeworld Ekos while trying to organize a new holocaust on a neighboring planet called Zeon. Before murdering his mentor, Melakon was denounced by him as nothing more as a self-seeking adventurer, a traitor to his people and all they stood for.
* CrowningMusicOfAwesome: Samuel Matlovsky's arrangement of strings and bass captures the combination of humor and seriousness of the situation in "I, Mudd."
* EarWorm:
** Alexander Courage's theme music.
** [[http://www.youtube.com/watch?v=_dnZHea_TI0 Gerald Fried's 'Ancient Battle' theme]] for "Amok Time", which has been spoofed in ''TheCableGuy'', ''WesternAnimation/{{Futurama}}'' and ''WesternAnimation/{{The Simpsons}}''. '''Dun-Dun-DUN-DUN-DUN-DUN-DUN-DUN-Dun-Dun-DUN-DUN'''...
** From the same composer, the piece that plays throughout the episode "Shore Leave" often referred to as "Finnegan's Theme".
** It took decades, but La-La Land issued ''all'' the series' original music in a 15-disc set in 2012.
* EnsembleDarkhorse: Hikaru Sulu's popularity has gone ''way'' up in recent years, in no small part due to {{George Takei}}'s newfound prominence as a civil rights activist. Having an insane number of followers on {{Facebook}} and {{Twitter}} doesn't hurt either.
* EscapistCharacter: Spock, for socially awkward Trekkies. Spock is smart, respected, physically powerful, long-lived, and blessed with loving and devoted friends even though he himself has never learned human social skills. The fact that he was picked on as a child on Vulcan as a "Half-Breed" further cements how much you can identify with him.
* FairForItsDay:
** Uhura: Although now it seems normal and unremarkable for a woman to have a job other than a secretary, back then Uhura being in a ([[MildlyMilitary almost military]]) job and being black was a huge leap forward.
*** Not only that, even when she primarily served as TheChick, casting a ''[[HumansAreWhite black]]'' woman in the role was a huge deal in the 1960s. (A black woman who sat at ''rear center stage'', right behind the Captain's seat where viewers could not possibly miss seeing her. Holy diversity, Batman!) And novels written as early as the '70s indicate that Uhura was far more than a glorified switchboard operator -- she is in fact a linguistic genius who can leave Kirk's head spinning with language theory. Even in the episodes, there are occasional hints of her mechanical abilities implying that she can take apart and fix the communications equipment as well as operate it. Also, Uhura was technically fifth in command of the ''Enterprise'' (and did take command for at least one episode of the animated series) meaning that out of the ''entire crew'' only Kirk, Spock, Scotty, or Sulu could override her decisions (although in one episode MauveShirt [=DeSalle=] takes command ahead of her).
*** One story going around is that Nichelle Nichols was considering leaving the show at one point, but Martin Luther King, Jr. himself told her how much the world needed to see an African-American woman on television being treated as an equal by white characters.
** Sulu: Not to the same degree as Uhura, but it does not seem particularly notable or progressive today to have an Asian supporting character while all the leads were white. However, in the 1960s, it was a ''pretty big deal'' that Sulu had no accent, did not do martial arts, and overall was not an offensive stereotype of Asians. Just about every Asian-American actor was clamoring for the role as a result.
*** Having an Asian on the bridge would raise more than a few eyebrows among older viewers, especially since it was pretty obvious he was Japanese.
*** Of course, martial arts did eventually creep into Sulu's character by the third movie, and one animated series episode has a slightly uncomfortable joke about Asian racial stereotypes.
*** Martial arts training would make sense for an officer in a [[MildlyMilitary (quasi)military]] organization, Asian or not.
*** And he was going to have a big martial arts scene in "[[Recap/StarTrekS2E16TheGamestersOfTriskelion The Gamesters of Triskelion]]" before Takei had to bow out of the episode, resulting in him being replaced with Chekov and the scene becoming a standard '60s TV fight.
*** According to Takei's autobiography, the writer of the episode "The Naked Time" asked him if he wanted Sulu to swordfight with a rapier or a katana. Takei chose the rapier because he felt the katana would be too stereotypical.
** While marred by the pop-culture idea that he's a playboy, the fact remains that even for today's standards, Kirk is one of the few male heroes who use the stereotypically feminine technique of using their sexuality to get information.
** Having a Russian character on American TV ''at all'' in the 1960s, let alone making him one of the show's protagonists and showing him to have the main responsibilities over a military(ish) vessel's weapons system, was also pretty revolutionary for its time.
* FamilyUnfriendlyAesop: TheReveal in "The City on the Edge of Forever" that Edith ''has'' to be killed, else her pacifist movement will keep America out of World War II and result in the Nazis developing atomic power first and winning, ultimately sums up as one of these. "Pacifism is an ideal to aspire to, but reality is more cynical, and sometimes people must be prepared to fight." It's not necessarily a ''bad'' aesop, but it's certainly more cynical than you'd expect of a 60s show, and in rather stark contrast to the pretty strong "Pacifism = Good" message sent by earlier episodes.
* FanficFuel:
** The Guardian of Forever has appeared in dozens of Star Trek novels.
** "Mirror, Mirror" provides a particularly rich vein of it, letting fans come with versions of any episode across the franchise from the Mirror Universe. And in the case of ''Next Generation'' and ''Voyager'' episodes, this includes building the Mirror cast from scratch.
* {{Fanon}}
** Trelane was [[Series/StarTrekTheNextGeneration a member of the Q Continuum]]. Or, indeed, possibly even the ''same'' Q who later encounters Picard...
** [[WordOfDante Confirmed]] by PeterDavid in his TNG novel ''Q Squared''. Trelane is even implied to be [[spoiler:Q's illegitimate son.]].
** The (technically) two seasons which compromise ''WesternAnimation/StarTrekTheAnimatedSeries'' are actually the fourth and fifth year of [[FiveYearPlan the five year mission]] mentioned in the opening credits. The animated series isn't a different show, but the same one. Except it's a cartoon.
** It's commonly speculated that Janice Lester in "Turnabout Intruder" was deemed too mentally unstable to command a starship and her psychotic mind twisted it into thinking that ''all'' women were forbidden from holding that position. This is more or less promoted to canon in ''Enterprise'', which casually revealed that Starfleet ''does'' allow women captains.
*** [[http://fanlore.org/wiki/Shatner:_Where_No_Man#Nimoy_and_Shatner In interviews for a book about Shatner, Nimoy confirmed]] that Roddenberry was indeed saying women can’t be captains, that they cannot do all that men do. "What Roddenberry set out to prove was that this lady, given command of the ship, would ''blow it''." He had voiced repeated objections to this during production.
* FanPreferredCouple (so very, very much so it spawned the first SlashFic. Yep, Kirk and Spock again...)
* FightSceneFailure: [[http://www.youtube.com/watch?v=aSno7_DcNyw Behold]].
* FirstInstallmentWins
* FunnyAneurysmMoment: After Kirk drops the LogicBomb on Nomad in "The Changeling", he jokes, "It's not easy to lose a bright and promising son....My son, the doctor." [[Film/StarTrekIIITheSearchForSpock He later finds out how right he is.]]
* GrowingTheBeard: [[AvertedTrope Averted]] by the series proper, the only ''Franchise/StarTrek'' series with a strong start. Among the movies, definitely ''[[Film/StarTrekIITheWrathOfKhan The Wrath of Khan]]'' - see also SurprisinglyImprovedSequel or EvenBetterSequel, depending on your view of the first.
* HarsherInHindsight:
** Evil Kirk's assault of [[BrotherChuck Rand]] during "The Enemy Within" is pretty awful in light of the fact that Grace Lee Whitney was later sexually assaulted by one of the ''[[Franchise/StarTrek Trek]]'' producers.
*** You can go ahead and say it. It was Gene. It's very clear in her book. Leonard Nimoy knew about it and supported her.
** In the episode "Assignment: Earth", Spock lists several scenarios that Gary Seven could have been sent to effect in 1968 Earth. One of them is "an important assassination". The episode aired March 28, 1968. MartinLutherKingJr was assassinated on April 4, 1968. To twist the knife even further, Robert Kennedy's assassination occurred just two months later.
** In the aftermath of incidents like the Manson murders, Dr. Sevrin's actions in "The Way To Eden" become a lot more disturbing.
*** He was originally meant as a Timothy Leary {{Expy}}, of course, but long before the Manson murders, people clearly had the idea that something like that ''could'' happen. Stories about rock- and acid-addled hippies running criminally amuck, obeying an insane or evil "guru", were rife. There was even one in ''Jimmy Olsen'' comics, "[[http://dc.wikia.com/wiki/Superman%27s_Pal,_Jimmy_Olsen_Vol_1_118 Hippie Olsen's]] [[http://misfitdaydream.blogspot.com/2013/10/freak-out-with-jimmy-olsen-angry-hippie.html Hate-In]]" (dated March 1969, it probably hit the stands in early January, seven months before the Manson killings).
** The message in "A Taste of Armageddon", about the dehumanizing effects of computerized warfare, was haunting enough in 1967, when the computer was still in its infancy. Today, with things like [=UAVs=] and computer-guided missiles becoming indispensable parts of modern warfare, it hits harder than ever.
** "Space Seed" ended with Kirk delivering a very optimistic line about the [[Film/StarTrekIITheWrathOfKhan future of Khan's people...]]
** "The Menagerie" when you consider that Jeffery Hunter (Captain Pike) was later injured in an on set explosion on a film set that eventually caused him to be partially paralyzed and lose his power of speech. Eventually, he recovered but later still died from a cerebral hemorrhage caused by the explosion.
** In "Wink of an Eye," Kirk hears the hyper-accelerated aliens of the week as an annoying buzzing. William Shatner contracted permanent tinitus from an explosion on the show.
** "The Cloud Minders" feels remarkably similar to the mass lead poisoning going on at the time, which wouldn't be discovered for a while longer.
* HeartwarmingInHindsight: In "Errand of Mercy", the first episode to feature the Klingons, the Organians speculate that someday, the Federation and Klingons will become allies. In ''Series/StarTrekTheNextGeneration'', we see this indeed came true, and how it happened is explored in ''Film/StarTrekVITheUndiscoveredCountry''. According to ''Series/StarTrekEnterprise'', by the time of the 26th Century, the Klingon Empire will officially join as a member of the United Federation of Planets.
* HilariousInHindsight:
** In the first pilot, "The Cage", Vina on Number One's breeding capabilities: "You'd have better luck with a computer!" During the episode's use in "The Menagerie" it was just plain funny, as Majel Barrett had already been voicing the computer for some time.
** Leonard Nimoy playing an emotionless alien might have been if ''Film/InvasionOfTheBodySnatchers'' had been a bigger phenomenon than ''Franchise/StarTrek''.
** Uhura's teasing Spock in song in "Charlie X" in light of the [[Film/StarTrek recent movie.]]
** In "The Corbomite Maneuver", Bones needles the svelt Captain Kirk over having put on a few pounds. In more recent years, William Shatner has been having issues with his spare tire.
** ''WesternAnimation/TheSimpsons'' has made it somewhat more difficult to be suitably grave about the possibility that a character in "The Conscience of the King" is the notorious Kodos in disguise.
** Spock's surprised reaction to his first sight of the Romulans in "Balance of Terror" could now come off just as much as a reaction to the commander looking like his father.
** Cogley's defence of Kirk in "Court Martial" partly rests on emotively arguing that man is superior to machine and the court therefore should not take it for granted that the computer's evidence is inviolate. A couple of decades later, ''Series/StarTrekTheNextGeneration'''s own courtroom episode "The Measure of a Man"--which even also includes the legal FightingYourFriend trope--is about proving that a machine can be equal to man.
** Jame's outfit in "Court Martial" is nigh-identical to a [[Anime/SailorMoon Sailor Scout's]].
** "The Return of the Archons" features a society that is orderly and well-behaved except during a regular twelve hour period of complete anarchy. [[Film/ThePurge Seems familiar.]]
** Mirror Sulu's lecherous interest in Uhura in "Mirror, Mirror". It really is a mirror universe, [[ActorAllusion Ohhh Myyy!]]
** Spock once remarks that "the most unfortunate lack in current computer programming is that there is nothing available to immediately [[Series/StarTrekVoyager replace the starship surgeon]]."
** In the rejected first pilot episode, Captain Pike, Kirk's predecessor, annoyed with his crewmates, says, "What are we running here, [[Film/StarTrek a cadet ship]]?"
*** This was hilarious in hindsight as far back as ''Wrath of Khan'': the Enterprise was meant to be on a training cruise before flying off to deal with Khan and was largely full of cadets.
*** Captain Pike irritably asking Number One "are we running a cadet review?" takes on a whole new, unintended meaning in context of his role in the 2009 film.
*** Number One is derisively compared to a computer, when Majel Barrett would spend the rest of her life voicing computers in the franchise.
** In "The Way to Eden" one of the female space hippies tries to seduce Sulu, who doesn't bite. And says "How do you know what I want?" with a giant grin on his face.
** ''Film/RevengeOfTheSith'' was not the first sci-fi production to have a doctor diagnose a patient with a fatal deficiency of will to live.
** Compare the older versions of Spock, [=McCoy=] and especially Kirk in "The Deadly Years" to how they really turned out.
** In "Day of the Dove", Spock and Scotty warn Kirk about the dangers of intra-ship beaming. In ''Film/StarTrek'', Spock Prime (this Spock) reveals to Scotty that Scotty Prime eventually created a formula for interstellar beaming, which would explain how intra-ship beaming becomes commonplace by the 24th century.
** In the episode "Metamorphosis", Zefram Cochrane's reaction to seeing the Federation commissioner essentially amounted to "Hey hot girl, let's jump in bed together!". Young healthy male marooned on planet for decades + newly marooned female = Hormone explosion; doesn't really take lot of analysis to see why he'd be all over her... but then in ''First Contact'',back in the 21st century, Troi was complaining about how she'd gotten roped into drinking with Cochrane and spent a lot of time fending off all of his drunken efforts to grope her. If anything, he's improved! Arguably, an intentional CallForward.
** "Is There No Truth In Beauty?" features [[Series/StarTrekTheNextGeneration A. a blind person and B. a device called a Visor]].
* HoYay: Spock had so much of this with Captain Kirk that entire [[WebVideo/TheShipsCloset web shows]] and essays have been devoted to it, and it spawned SlashFic as a genre. But his SlapSlapKiss with Dr. [=McCoy=] shouldn't be ignored...
** It should be noted that the creator has said that Kirk and Spock's [[http://en.wikipedia.org/wiki/Kirk/Spock#Origins_and_creators.27_responses "affection was sufficient" for "physical love" "had that been the style of the 23rd Century"]]...but, I suppose that may vary?
*** Roddenberry was maneuvered into voicing this speculation by Sondra Marshak and Myrna Culbreath, who were working on the Shatner bio [[http://fanlore.org/wiki/Shatner:_Where_No_Man Shatner: Where No Man]]. It was supposed to be a comparison of Kirk and Spock with AlexanderTheGreat and his second-in-command/lover Hephaistion. In the full quote Roddenberry admits the "lovers" idea had ''not'' occurred to him before the ladies suggested it.
** See the trope page itself for many, ''many'' more examples.
* IAmNotShazam: The planet killer is consistently referred to as just that -- however, it is sometimes remembered as the "Doomsday Machine", that being the name of the episode and everything.
* IronWoobie - Spock is perfectly willing to sacrifice himself for others. He will also stand by his principles even when he expects that Kirk, [=McCoy=], or his parents will hate him for it.
* JerkassWoobie: Decker in "The Doomsday Machine". We feel bad for him since he's mourning the loss of his crew. Still, he can be a real jerk.
* LikeYouWouldReallyDoIt: Several episodes try to wring tension from a main character's supposed death, most notably "Amok Time." Also, Spock's blindness from "Operation: Annihilate!" Given that the show is from the era of strict StatusQuoIsGod, the ending is never in doubt.
* MagnificentBastard:
** T'Pring in "Amok Time." Vulcan marriage/divorce laws are ''very'' restrictive--betrothal from age seven, and no possibility of divorce except during the Pon Farr. As the years went by, T'Pring decided she didn't want to marry a distant, legendary figure and would rather be with a Vulcan she actually knew and liked, so she chose to challenge the marriage and chose Kirk as her champion. If Kirk won, he wouldn't want her, and she could be with Ston. If Spock won, he would still free her for bringing the challenge at all--or he would leave, and she could still be with Ston on Vulcan. Picking Kirk ensured that Ston would not die in the combat. As Spock said, flawlessly logical. Not especially ''nice'' to Kirk, but still pretty good as cunning plans go.
** Khan Noonien Singh in "Space Seed". In the briefing room, Kirk, Scotty and others discuss their secret admiration of Khan the historical figure, to the complete bemusement of Spock. They eat their words when Khan's barbarism and complete psychopathy are revealed. Even then, [=McGyvers=] follows him willingly in exile to the savage planet.
* MexicansLoveSpeedyGonzales: Scotty has a big fanbase among Scottish Trekkies.
* MyRealDaddy: Gene Roddenberry was responsible for the series as a whole, but one of his producers/writers, Gene Coon, had a great deal to do with making the show great with classic ideas like the Klingons, the Prime Directive, Khan Noonien Singh and being the series' showrunner in the first two seasons who helped many of the stories used better.
* {{Narm}}: Some aspects of the show have aged ''horribly'', especially for people born after 1990; as a result, this trope ends up popping up in places where it's obvious that wasn't the intent at all. Of course, a lot of people don't see this as a ''bad'' thing, as noted directly below.
** There are so many examples it'd be impossible to list them all, but one that stands out is the episode "The Omega Glory", in which another planet [[HollywoodEvolution evolves the American flag and constitution]], all for Kirk to make a ridiculously over-the-top patriotic speech about how [[{{Eagleland}} America is one of the best countries in the world!]] Even Americans find that scene ridiculous.
*** And did at the time. That episode, sneeringly referred to by some fans as "The United States of ''Star Trek''", was universally decried as scraping the ''bottom'' of the bottom of the barrel.
** Once you're familiar with the concept of {{Redshirt}}s, it's pretty hard to take their deaths seriously. Indeed, when you're thinking, "Yup, that guy's dead" as soon as they beam down, then when the time comes it can produce chuckles.
** [[http://www.youtube.com/watch?v=Z1eFdUSnaQM Some of the fight scenes aren't quite as terrifying as they were supposed to be]].
** [[http://www.youtube.com/watch?v=UhQA-06kSLU McCoy's face at the end says it all]].
** Kirk's "No Blah Blah Blah" line in "Miri".
* NarmCharm: To the point where many fans decry the remastered episodes as losing much of what made the show memorable to begin with.
* NeverLiveItDown:
** William Shatner is often the butt of jokes for his {{Large Ham}} delivery that quickly alternates between drawn-out and rushed. He actually didn't get like this until the third season, where the quality of material he had to work with took a significant drop.
** Kirk's reputation as a careless manwhore. He did sleep around a lot, but if he wasn't being a male FemmeFatale, amnesiac, or mind-controlled, it was a sincerely felt attraction that failed because of the woman's death or his "marriage" to ''Enterprise''.
* NewerThanTheyThink: Though this show is Creator/GeorgeTakei's most significant acting credit, by quite a large margin, it did not spawn his famous CatchPhrase "Oh ''myyyy...''". You can thank ''Radio/TheHowardSternShow'' for that one.
* NightmareFuel: Has [[NightmareFuel/StarTrekTheOriginalSeries its own page]].
* OlderThanTheyThink: the concept of transport beaming between star systems. It was introduced into Trek canon in the episode "[[Recap/StarTrekS2E16TheGamestersOfTriskelion The Gamesters of Triskelion]]".
* OnlyTheCreatorDoesItRight: The third season, which was the weakest, was the only one without Creator/GeneRoddenberry's oversight.
* RelationshipWritingFumble: If Kirk and Spock weren't intended to be in love with each other from day one, ''Franchise/StarTrek'' is guilty of quite possibly the greatest RWF in television history.
* SeasonalRot:
** As the show went on, the missions just kept getting weirder and weirder. Prime examples include looking for Spock's brain, a showdown at the O.K. Corral and encounters with hippies, Chicago Gangsters, Native Americans, a modern day Roman Empire, [[ThoseWackyNazis Nazis]], Abraham Lincoln and even the Greek god Apollo. Though most fans point to Roddenberry stepping out of day-to-day involvement at the start of Season 3, some fans believe that the show was already running out of steam in the latter third or so of Season 2, and point to the departure of Gene L. Coon midway through that season as when things started going wrong.
** In fact, the episode "Spock's Brain" is usually regarded as the absolute worst episode in at least the original series and sometimes in the whole of ''Franchise/StarTrek''.
** Given a LampshadeHanging in some of Kirk's in-universe biographies, which typically note that many of Kirk's reports were met with considerable disbelief from his superiors in Starfleet. The case where an alien race literally stole Spock's brain is usually mentioned in an especially disdainful manner.
* SeinfeldIsUnfunny: ''Fwoof''. TOS catches it ''bad'' these days. Not only has everyone who followed in its footsteps borrowed from it to some degree, but they've ''all'' tried to improve upon a lot of the problems the show had due to a limited budget, technological barriers of the time and the fact that the cast and crew were inventing a lot of tropes as they went. Fans who got into Trek with the newer installments can have trouble watching TOS nowadays.
* {{Shipping}}: Kirk/Spock is obviously a near-legendary example of this, with other common pairings being Scotty/Uhura (mostly in an attempt to do their romance from ''Film/StarTrekVTheFinalFrontier'' in a way that doesn't seem completely insane) and Sulu/Rand (due to the two's interactions in "The Man Trap" and the fact that Rand later wound up on the ''Excelsior'').
* [[SoBadItsGood So Bad It's Good]]:
** "[[Recap/StarTrekS3E1SpocksBrain Spock's Brain]]" is so awesomely bad that, when you approach it the right way, it becomes one of the funniest Trek episodes ever made. Rumor has it that the script originated as a prank at the expense of Creator/GeneRoddenberry. C'mon, say it, people:
--> "Brain and ''brain!'' '''What is BRAIN?!'''"
** The episode "The Omega Glory". There's something about that American flag. The Pledge and the Spock-like Satan illustration did not help. Shatner's trademark delivery worked well when he said, "Look at these words...written bigger... than the rest... tall words ... proudly saying ... 'We... the Pe... ople...
* SomeAnvilsNeedToBeDropped:
** "Let That Be Your Last Battlefield." Racism is self-destructive and it makes no ''sense'' to consider people "inferior" based on purely aesthetic features. Note that the episode aired just one year after the assassination of Martin Luther King, Jr.
** "The Omega Glory" is divisive, [[AmericansHateTingle particularly among international fans]], but it pulls no punches about how dangerous blind patriotism and nationalism can be.
* SpecialEffectsFailure:
** So many monsters... [[http://fc00.deviantart.net/fs50/f/2009/336/3/5/Yay_60__s_by_CatNipSoup.jpg and the space-dog that is clearly a dog]].
** In "Tomorrow Is Yesterday", it turns out that optical effect of the ''Enterprise'' doesn't work very well against the sky. It can be pretty laughable when they say they're going incredibly fast and then we see the ship looking like it's barely even moving.
** In "The Alternative Factor", that constant "winking" effect with the overlays of a nebula and two ghostly figures struggling against each other. It was probably trying to be arty, but it comes across as pretentious, confusing, and just plain boring. All the scenes that get cut for syndication, and they couldn't reduce any of this useless {{Padding}}?
* StoicWoobie: Spock definitely falls into this category. He's an alien to two races, and several times he is injured in the line of duty, or stands by his principles under severe criticism. A few episodes that highlight this are "Journey to Babel", "Operation: Annihilate", and "The Tholian Web".
* StrangledByTheRedString: Happens several times in Season 3, with Kirk genuinely falling in love rather than the pragmatic manipulation he'd done before. The worst is "Requiem for Methuselah," where it explicitly happens within ''four hours''.
* TearJerker: Has [[TearJerker/StarTrekTheOriginalSeries its own page]].
* TheissTitillationTheory: The TropeNamer was the series costume designer, William Ware Theiss.
* TheyChangedItNowItSucks: For those who dislike the "remastered" episodes (and especially resent that CBS is obviously trying to supplant the original versions with them - though at least they aren't going [[OrwellianEditor full Lucas]]).
* TheyJustDidntCare: One of the most prominent continuity errors in the entire series occurs in "Charlie X" when Kirk enters the turbolift with Charlie wearing his gold uniform top...and emerges with the green wraparound on. The only internally consistent explanation would involve the single most awkward elevator ride ever as Kirk changed his top in front of Charlie. (Or maybe Charlie changed it as a joke in the turbolift while talking with Kirk and Kirk didn't notice.)
** In "Turnabout Intruder," the director ordered Shatner to exit the conference room the wrong way to get the shot he wanted, which Shatner pleaded against to no avail.
* TheyWastedAPerfectlyGoodPlot:
** In "Miri," the discovery of a planet identical to Earth on the other end of the galaxy is completely forgotten about after the first act, when it probably could have supported a whole story arc if the show hadn't been made in the era of absolute StatusQuoIsGod.
** The idea of a man going insane when he learns he has a double from another universe and wants to kill said double at all costs is one of the more interesting concepts in the series. Unfortunately, the episode "The Alternative Factor" does little to effectively build upon it.
** The so-called Hippie episode (The Way to Eden) believe it or not. We learn here that the artificial atmospheres the Federation use (including the one on the Enterprise) are breeding extremely powerful diseases that apparently cannot be cured. If we actually had a ''Khan-level'' villain who had been infected here instead of the ridiculous one we actually got, we could have had the crew battle an horrific plague whilst trying to prevent an invader from stealing the ship.
*** Plus, the idea that there would be rebellion against authority even within the supposed Utopian future of the series. The franchise would later revisit this with far more attention with the Maquis, though even then not much was really done with the idea of questioning how perfect the Federation really is.
** [=McCoy's=] illness in "For the World is Hollow and I Have Touched the Sky." Just imagine what a modern day show could do with a character having a fatal disease and racing against time to find a cure, rather than knowing it'll be fixed somehow by the end of the episode.
* [[TookTheBadFilmSeriously Took The Bad Episode Seriously]]: Creator/DeForestKelley, an old-school character actor, made a living out of doing this, and carries on with it throughout the series, with aplomb. Contrast Creator/WilliamShatner and ''especially'' Creator/LeonardNimoy, both of whom visibly [[TheyJustDidntCare stop trying]] whenever the writing is particularly sub-par.
* UncannyValley: “Nancy” while she was stalking Rand’s salt. Creepy.
* UnderminedByReality: Gene Roddenberry's vision of a future moneyless utopia falls rather flat when you learn that the man himself was a quite ruthless businessman, pulling shady moves like writing completely irrelevant lyrics to the show's theme song that were never intended to be used just so he could steal part of the composer's paycheck. Though you can still argue that the "idea" itself is more important than the flaws of the man behind it.
** Of course, the "moneyless society" concept was [[NewerThanTheyThink never part of the original series.]] The episodes with Harry Mudd and Cyrano Jones make it very clear that money ''does'' exist. The "we don't use money in the future" idea first appears decades later in a throwaway line in ''Film/StarTrekIVTheVoyageHome,'' and frankly seems to just come out of the blue. It would be ''Series/StarTrekTheNextGeneration'' that made it a central aspect of the setting.
* ValuesDissonance:
** In "The Enemy Within", Rand's first instinct after Evil!Kirk tries to rape her is to cover for him. And note that she actually thinks it was Kirk himself! Even the blocking of the scene is unnerving these days, with the three guys all looming over the distraught Rand in what certainly seems like the position most likely to dissuade her from talking about it.
*** In one magazine interview, Grace Lee Whitney points out that Spock even seems to be a little turned on by the whole situation, as during Rand's public apology to Kirk at the end of the episode (and yes ''she'' apologizes to Kirk and not the other way around) he states ''the imposter had some interesting qualities wouldn't you say?'' before obviously leering at her as she walks away. She also states in another [[http://trekmovie.com/2006/10/16/interview-grace-lee-whitney-talks-past-and-future-rands/ interview]] that her directions for the rape scene from Gene were to make it ''real but glamorous,'' which frankly are two words that go together like fire and water.
** In "Who Mourns for Adonais?", Kirk and Bones regret the upcoming loss of a skilled female officer given what seems like her impending marriage to Scotty, with no thought to the possibility that a married woman would keep her job. Making it weirder is that the previous season's episode "Balance of Terror" featured two crew members getting married with no explicit mention of the woman quitting her job.
** "Elaan of Troyius" is a sci-fi take on ''Theater/TheTamingOfTheShrew'' played absolutely straight. Note that the play's horrific sexism had already started being mocked even while Shakespeare was still alive.
* ValuesResonance: Several episodes, like "A Taste of Armageddon", and most notably, "Let That Be Your Last Battlefield".
* VisualEffectsOfAwesome:
** The true form of the salt vampire in "The Man Trap" is one of the show's most impressive (and scary) aliens. Too bad we don't get to see it for long.
** The effects in "Who Mourns For Adonais?" are pretty good even before the digital remastering. Subtle but effective: swaying trees and bird song make the studio set look like it really is outside. We really do believe from the arranged shots that Apollo is growing. However, even modern SFX can't keep a giant green hand in space from looking a little silly.
* WhatAnIdiot:
** Joe Tomerlin, the RedShirt who accompanied Spock down to the planet at the beginning of "The Naked Time". He takes his protective glove off, puts his hand down on the surface of a planet where many people have died with no explanation, and scratches his nose with the same hand. Before he stabbed himself, he claimed that humanity didn't belong in space. Given his [[TooDumbToLive horrific failure to follow basic hazmat procedures]] on a space station where everyone has died for no evident cause, perhaps it was only ''he'' that did not belong in space.
** Bones grabs the IdiotBall in "The Alternative Factor". They got Laz in sick bay. Bones says he's "not going anywhere. Not this time." after telling a muscley RedShirt to take a hike. Bones and Kirk then walk off, leaving Laz unattended. Bones even lingers by the doorway, as if trying to remember something he forgot. Oh yeah, he should've either tranqed or restrained the madman who was trying to steal the dilithium crystals!
* TheWoobie:
** Miri in "Miri", when she cries and begs Kirk and co. not to hurt her.
** Apollo in ''Who Mourns for Adonais''.
** Alexander in "Plato's Stepchildren", after being used for centuries as Parmen's ChewToy.
** Spock is seen as this by many fans.
** [=McCoy=] has his woobie episodes in "The Empath" and "For The World Is Hollow And I Have Touched The Sky".
** Chekov. While every one of the main cast gets into their fair share of trouble, it always seems to pull at your heartstrings a bit more when it happens to poor adorable Chekov. Additionally, the BigBrotherInstinct Kirk seems to feel towards him is rather d'aww-inducing, particularly the way Kirk calls him by his first name when he's been hurt.
** Yeoman Rand. Of the first four episodes aired, three of them had her having to fend off unwanted male attention (though the first one of them was actually a shapeshifting alien, as if that makes it any better for her.)
* WTHCostumingDepartment: In "The Alternative Factor", Robert Brown seems to be wearing a different fake beard in just about every scene.
