!!The TV series:

%%Do NOT add CompleteMonster entries without going to the cleanup thread first.
* CrowningMusicOfAwesome: Lalo Schifrin's iconic theme tune, still used in parodies and commercials to this day.
** Special mention to Schifrin's scoring during the church climax of "The Heir Apparent" with Cinnamon trying (with some previously supplied help from Barney) to open a puzzle box that only the woman she's impersonating - [[NoCelebritiesWereHarmed who is absolutely not Anastasia]] - could have opened; this particular cue gets reused often in later episodes. [[spoiler: And yes, she does get it open.]]
*** You can now get a boxset of music from throughout the series, via La-La Land.
* EarWorm: It goes hand-in-hand with the Crowning Music of Awesome. '''Everybody''' knows the ''Mission Impossible'' theme song.
** If you watch a few episodes, you'll also find the incidental music running through your head.
* EnsembleDarkhorse: Landau quickly eclipsed star Steven Hill, even though he was only intended as an occasional guest star.
* FairForItsDay: [[BlackAndNerdy Barney Collier]], played by [[ Greg Morris]], was TheSmartGuy in a band of geniuses. Also, while Cinnamon's primary task was to provide distractions, everyone treated those distractions as vital, and Cinnamon was clearly a respected team member.
* HarsherInHindsight: "Action!" centered around [[FramingTheGuiltyParty a staged film purporting to show atrocities committed by American troops in Vietnam]]. In light of what was later revealed, it gets uncomfortable fast. On the other hand, the episode also takes some self-deprecating jabs at the movie business and this part resonates as well as it ever did. Some things never change.
* HilariousInHindsight: In "Encore," William Shatner plays a 60-year-old gangster who's de-aged by the IMF for several hours. The show's idea of an old William Shatner is a bit at odds with how he really turned out...
* HollywoodHomely: "Homecoming" features a mystery concerning the murders of young, beautiful women. [[spoiler: It turns out that the killer is a local barmaid, ostensibly unattractive, who is jealous of how much attention the pretty women get from a man she is in love with. The homely barmaid is played by [[Series/{{MASH}} Loretta Swit]].]]
* LikeYouWouldReallyDoIt: One episode features a plan that requires one of the agents to go to jail for years in order to sell the cover story. It's emphasized in the briefing that he should not expect a rescue, since that might draw suspicious attention to his cover, and he's prepared to go through with it for the greater good, but inevitably there's an unforeseen change of circumstances and the rest of the team have to rapidly come up with a plan to break him out after all.
* MagnificentBastard: So ''very'' many.
** Special mention has to go to Briggs, however. This was a guy who, in "The Carriers," left an entire town of Russian spies ''to die from bubonic plague.''
* MemeticMutation:
** The show's whole concept - ImpossibleMission is a trope of its own.
** The theme tune still represents clever operations to outwit a target, from jewel heists to squirrels looking for nuts.
** "[[ThisPageWillSelfDestruct This tape will self-destruct in five seconds]]" - especially popular for parodies, where the self-destruct is often over-powered and bad news for the person close to it.
* {{Narm}}: "Some of that dialogue is terrible, isn't it?" - ''Mission: Impossible'' writer-producer William Read Woodfield. Example, from "A Game Of Chess" (which Woodfield and his partner Allan Balter, in fairness, did ''not'' write):
-->'''Jim''': Then we're all set except for the typhoid. Who's got it?
-->'''Rollin''': I do.
* NarmCharm: The series is ridiculous and often centers around problems governments would generally solve in a far more straightforward way (as Martin Landau pointed out, "In reality, there'd be an assassination"). But it's still a lot of fun to watch.
* ReplacementScrappy: Dr. Doug Robert for Willie Armitage in most of the fifth season. He was written out early on in season 6 while Willie returned to the IMF team full time.
* ValuesDissonance: Originally, the IMF were a group of people choosing to use their specific talents in spy work purely for the good of their nation. (Starting in 1966, still the era of "[[UsefulNotes/JohnFKennedy Ask not what your country can do for you, but what you can do for your country]].") This wouldn't have worked in the 1996 movie, so it made the IMF a deeply covert part of the US intelligence services. Even in the time of UsefulNotes/RichardNixon, the idea of American agents covertly manipulating foreign countries as heroes was going out of fashion, and in later seasons the IMF spent most of their time working their wiles on organised crime at home. (Although in the revival and the movies they got to travel around the world again.)

!!The first film:

* AlternativeCharacterInterpretation: [[spoiler:Did Phelps betray his country because he simply thought they weren't paying him enough (with spy work not living up to his expectations), or was Phelps [[ShellShockedVeteran on the verge of a psychotic breakdown during his missions as a field agent]], before eventually snapping and becoming a treacherously delusional, AxCrazy, [[TheSociopath sociopathic]] {{mole}} that led to the events of the first film?]]
* BetterOnDVD: When it was released in theaters, many people regarded the first film as being extremely difficult to follow, albeit with a great final act making up for things, which in no small part was responsible for the ActionizedSequel nature of the second film. With the benefit of home video releases however, a lot of people have come to appreciate the more nuanced plot of the first film.
%%Do not add any other entries without going to the cleanup thread first.
* NarrowedItDownToTheGuyIRecognize: [[spoiler:Jon Voight turns out to be the first film's villain.]]
* SugarWiki/NoProblemWithLicensedGames: The ''VideoGame/LegoDimensions'' Level Pack has received praise as an enjoyably lighthearted adaptation of the movie. It helps that Ethan possesses a wide assortment of skills.
* TheProblemWithLicensedGames: The UsefulNotes/{{Nintendo 64}} game. It was a stealth adventure that very loosely followed the movie's plot. Though a [[SoOkayItsAverage fairly decent]] game with some neat ideas, it suffered from bland (and often OffModel) graphics, [[ObviousBeta numerous bugs and glitches]], and frustrating TrialAndErrorGameplay.
* UnintentionallySympathetic: William Donloe, the CIA operative in charge of handling the NOC list at Langley. He gets spiked with a saline solution making him throw up uncontrollably, and he gets ReassignedToAntarctica when the team gets away with it in his incapacitated state.
