Works in this franchise with their own pages:

* ''YMMV/BackToTheFuturePartII''
* ''YMMV/BackToTheFuturePartIII''

!!Series-Wide:
* CrazyAwesome: None other than Doc Brown.
* EarWorm: Huey Lewis and the News' "The Power of Love" and "Back in Time" are hard to forget.
** As is the LeitMotif.
* EnsembleDarkhorse: "CPR Guy" from Part II. And for a short time in the fandom, the scarecrow that Marty runs over in Part I.
** Red the bum, who calls Marty a "crazy drunk driver" upon his return to 1985 in Part I, and a "crazy drunk pedestrian" in 1985-A in Part II.
* FanCommunityNickname: Backies.
* FirstInstallmentWins: The first is ''iconic''. The second and third are good, but definitely not remembered like number one.
* HilariousInHindsight: Creator/RobertZemeckis and Creator/StevenSpielberg's first concept for the time machine was not a [=DeLorean=]. Originally, the idea was that it would be a highly-scientific laser array that sent Marty back to the past. To get him [[TitleDrop back to the future]], Doc Brown originally was going to put him in a refrigerator during an A-Bomb test. Spielberg vetoed the concept back then out of fear that kids would climb into abandoned refrigerators and become trapped, not to mention it was incredibly expensive. [[Film/IndianaJonesAndTheKingdomOfTheCrystalSkull A couple of decades later, however...]]
* OneSceneWonder: Flea as Needles in the sequels.
* TheProblemWithLicensedGames:
** Played straight by the infamously awful games released for the NES and Genesis. [[SugarWiki/NoProblemWithLicensedGames Averted]] by the Telltale game and ''Super Back to the Future Part II'' for the [[SuperNintendoEntertainmentSystem Super Famicom]], which sadly [[NoExportForYou was only released in Japan]].
** The ''VideoGame/LegoDimensions'' ''Back to the Future'' Level Pack's Story Mode has received complaints of ItsShortSoItSucks, consisting only of four areas[[note]]five if the player can find the secret path to the Enchantment Under the Sea Dance[[/note]] that take 30 minutes to run through. Mitigated by the automatic addition of Marty [=McFly=] (who can use his guitar to break open certain boxes and doors with SONAR waves), the [=DeLorean=], and the Hoverboard to the player's party, and the ability to freely explore Hill Valley's town square in 1985, 2015, and 1885.[[note]]Even then, some reviewers have noted that a ''BTTF'' fan could save some money by purchasing the Doc Brown Fun Pack, and using the Doc minifigure to access the portal to freely explore Hill Valley. He also has different abilities than Marty does, such as hacking and controlling drones, and comes with the train from Part III.[[/note]]
* RewatchBonus: Parts II and III make greater sense when watched back-to-back, as you'll see signs of {{Foreshadowing}} and other details between the two parts. For instance, as Doc and Marty discuss their plan at the train station, you'll see that Clara Clayton was standing in the background waiting for someone to pick her up.
* SomeAnvilsNeedToBeDropped: The "Don't let your pride get the best of you" aesop they drill into your head in Parts 2 and 3. It's {{Anvilicious}}, but it is surprising how many people actually do put themselves into situations just to prove themselves to others.
* TheyWastedAPerfectlyGoodCharacter: Jennifer in the sequels. It's unfortunate that the writers saw her only as TheLoad, depriving her of some CharacterDevelopment.
* VindicatedByHistory: The sheer number of jokes about the approach and arrival of the year 2015 has definitely increased the notability of Part 2. This leaves Part 3 as the only one that isn't really iconic.
* WhatDoYouMeanItsForKids: Remember the joy of watching these films when you were a kid? Remember the scene where the second lead is ''gunned down by Libyan terrorists''? They sure don't make 'em like they used to. On the other hand, when Marty found himself in 1955, he made it a point to try and save Doc from his future fate... [[spoiler:and succeeds; it was more of an extremely delayed DisneyDeath.]] There's also Marty's plan to get George and Lorraine together at the dance involved him faking a rape attempt on his own mother, which was then broken up by a real rape attempt from Biff. It is generally believed that the movie most definitely would've received a PG-13 rating had it been released today, much like [[Film/WhoFramedRogerRabbit another Zemeckis film that came out later in the decade]].
-->"If my calculations are correct, when this baby hits 88 miles per hour, you're gonna see some serious [[PrecisionFStrike shit]]!"
** The first sequel isn't much better, starting with a GroinAttack on Marty Junior. Of course, the cherry on top is the alternate 1985 where Biff is a CorruptCorporateExecutive who murdered George in cold blood, forced Lorraine into marriage and breast implants, sits in a jacuzzi with naked women, and has turned Hill Valley into a hellhole.
** Part III has Buford hanging Marty, threatening Clara with rape, and attempting a slow death by bullet on Doc. Plus there's Doc's (implied) one night stand with Clara.
** Amusingly, this trope was why Creator/{{Disney}} turned down the first film, as they thought it was too raunchy, whereas many other studios thought it ''wasn't raunchy enough'' (this was the era of teen sex comedies like ''Film/{{Porkys}}'' and ''Film/RevengeOfTheNerds'').

!!Part I:
* AcceptableEthnicTargets: The Libyans. (With a bit of RippedFromTheHeadlines - Gaddafi ''was'' trying to acquire a nuclear weapon at the time.)
* AngstWhatAngst: Marty's mother pretty much shrugs off her AttemptedRape, and the fact that the man who attempted to rape her is working for the family thirty years later doesn't seem to cause her any noticeable distress.
* BrokenBase: Some fans take issue with the ending playing up the family's new possessions too much, saying it gives a very materialistic message.
* CoveredUp: Many younger people are first exposed to [[Music/ChuckBerry "Johnny B. Goode"]] and [[http://en.wikipedia.org/wiki/Earth_Angel "Earth Angel"]] through this movie, unaware of the originals.
* EndingFatigue: The film appears as if it is going to end at least twice before it actually does...
* FamilyUnfriendlyAesop: The first film also clearly sends the message that violence not only solves problems, but the ability to physically threaten others is directly related to social standing.
* FunnyAneurysmMoment:
** Before he was going to travel 25 years into the future by himself, Doc mentions that he'd get to find out who'd win the next 25 World Series. Then in ''Part II'', we see the horrific results of someone using future sports knowledge.
*** Plus, going ahead 25 years would put him smack in the middle of the US recession. Not exactly a time to visit to give you optimism for the future.
** The use of Middle Eastern terrorists as non-serious, throwaway villains in a ''family movie''. [[TheWarOnTerror Doesn't seem so innocent now, does it?]]
* GeniusBonus: Biff's goons are very intimidated by the Starlighters, saying "We don't want to mess with no reefer addicts." To many viewers, knowing that marijuana is not addictive and does not cause violent behavior, this may make them seem like cowards. Those familiar with the time period, though, will know that it was the era of ''Film/ReeferMadness'' and the goons had just bought into the propaganda. May double as a ParentalBonus.
* HarsherInHindsight:
** The angry Libyan terrorists shooting Doc Brown are less funny after the West Berlin disco bombing of 1986 and the bombing of Pan-Am flight 103 in 1989, both committed directly by or on orders of the Libyan government.
** At the start of the movie, a newspaper clipping is visible indicating that Doc Brown's mansion from the 50's burned down and he wound up selling the land to developers. In 2008, Christopher Lloyd's home in California, which he was selling at the time, burned down in the [[https://en.wikipedia.org/wiki/Tea_Fire Tea Fire]].
* HilariousInHindsight: "Gimme a Pepsi Free." That whole exchange is also a good example of WhosOnFirst.
** In the "Making Of" documentary, Creator/MichaelJFox expresses interest in travelling back in time to become a cowboy. Then, in Part III, he really does. He even lampshades this in the behind-the-scenes special for Part III.
** Doc says his [=DeLorean=] is electrically powered. In canon, this is nonsense because you can clearly hear an internal combustion engine which sometimes fails to start up. The need for gasoline becomes a plot point in the third movie. Fast forward to October 2011 when the [=DeLorean=] Motor Company announces the [[http://jalopnik.com/5850023/this-is-a-brand-new-all+electric-delorean DMCEV]] which actually ''is'' electrically powered. It runs on batteries instead of a 1.21GW nuclear reactor, though.
*** Doc was talking about the time travel equipment, not the normal functionality of the car. Given what happened in Part III, he probably should have had an electric engine put in in the future.
** The shopping mall in pre-time travel 1985 is named the [[WesternAnimation/GravityFalls Twin Pines]] Mall.
** One movie BTTF beat at the box office was Creator/ClintEastwood's ''Film/PaleRider''. In ''Film/BackToTheFuturePartIII'', the 1885 Hill Valley was shot at the same location used for ''Pale Rider'' and [[ImMrFuturePopCultureReference has Marty use the alias "Clint Eastwood"]].
** [[WhatCouldHaveBeen Originally]], Eric Stoltz was cast as Marty, while Creator/JeffGoldblum was considered for the role of Doc Brown in the first film. In the following year, Goldblum had an iconic eccentric scientist role of his own named Seth Brundle in ''Film/TheFly1986'', which spawn a sequel ''Film/TheFlyII'' which starred Stoltz as Seth's son Martin Brundle.
* HollywoodHomely: Marty's older sister Linda in the original 1985. Though not a model by any means, she's relatively cute and certainly not somebody you'd expect to have too much trouble finding a boyfriend.
* IdiotPlot: Several things that happen in this movie can be chalked up to foolish decisions by panicky individuals.
** When Doc sees the terrorists approaching, his first inclination is to fight back with an old pistol, instead of grabbing the plutonium, jumping into the [=DeLorean=] with Marty and Einie, and time travelling to somewhere in the immediate past or future.
** Marty freaks out George by impulsively staring at him and then following him, instead of simply seeking out 1955!Doc and getting the whole mess straightened out.
** Marty has ''just'' heard his parents' story of how they first met (he maybe heard it about five or six hours beforehand if you go by his own personal timeline), yet he deliberately interferes when he sees Sam Baines' car bearing down on George.
** Then there's the plot about making George seem heroic, which was extremely misguided on Marty's part. Why not just start an arguement with Lorraine, or insult her or something? Why go with forcing yourself on her?
** Thankfully averted by Doc, who changes his mind and decides to tape together the warning that Marty was hellbent on giving him.
* MemeticMutation:
** ONE POINT TWENTY-ONE GIGAWATTS!? (a reference to the amount of energy needed to power the Flux Capacitor the time travel)
** What the hell's a gigawatt?! (a reference to Marty's ignorance of what a gigawatt actually is)
** November 12, 1955. [[http://giveupinternet.com/2010/11/12/never-forget-november-12-1955-pic/ NEVER FORGET]].
** "It's your cousin Marvin Berry!"
** "Great Scott!" (This is usually what Doc says when he sees something surprising).
*** Become "Nom de Zeus!" (literraly "Zeus' name" but more akin to "Zeus dammit") in the French version.
** "Roads? Where we're going, we won't need roads." (Doc's closing line from the first film)
* MoralEventHorizon: Biff crossed it when [[spoiler:[[AttemptedRape he tried to rape Lorraine in 1955.]]]]
* MundaneMadeAwesome: [[http://www.youtube.com/watch?v=fwixq7fff-Q George ordering a milk. Chocolate.]]
* NarmCharm: Okay so Marty almost fading has some [[SpecialEffectsFailure bad green-screening]], but it's still tense and terrifying to see him almost ''fade out of existence''.
* SacredCow: Regardless of people's opinions of the [[ContestedSequel later movies]], the first is widely regarded as one of the best time travel movies of all time.
** Turns out, the image of the future Part II portrays stuck around in everyone's minds. The real-life 10/21/2015 ended up being something of a celebration of the series and The Future.
* SleeperHit: ''No one'' expected the movie to become as big as it did. Robert Zemeckis openly admitted he was just hoping it would break even and the final bit with the Delorean flying and "something's got to be done about your kids!" was meant as a joke on Marty having just changed the past for his parents. Michael J. Fox recalled his agent telling him that the movie was a hit and he was pleased, but the agent had to reiterate that it was a BIG hit.
* SpecialEffectFailure: The Bobs were never thrilled with the effect used to show Marty's hand fading from existence.
** Also, the green-screen shots of the flame trails not burning Doc and Marty are pretty obvious nowadays.
* {{Squick}}: Behind the scenes: the idea that every studio except Fox and Disney thought that this film, which features a boy's mother falling in love with her son, was not risque enough.
* StrawmanHasAPoint: Barely, since it relies on a coincidence Strickland couldn't have known about. He might be something of a jerkass to Marty at the beginning of the film when claiming he's a slacker who'll never amount to anything, but he is right that Doc Brown is dangerous, in a way - given he's not only willing to perform risky and highly illegal time travel experiments powered by stolen plutonium, but to rip off terrorists for said plutonium who might be out for revenge, and to allow Marty to be dragged into the situation.
* ValuesDissonance: In the DVD commentary, it's mentioned that some European audiences were put off by how the "improved" [=McFly=] family had become more materialistic, as exemplified by Marty getting the truck seen earlier in the film.
** Also to modern audiences, the implication that Creator/ChuckBerry was inspired to write his most famous song by hearing a white kid play it (Berry was an established, popular musician with a history of hit records years before "Johnny B. Goode" was released).
** The fact that the film, a mainstream, widely-popular and heavily beloved/referenced movie, involves incest not only as a major plot point, but ''PlayedForLaughs'', could also count.
* TheWoobie: George, before he TookALevelInBadass. The poor guy has been getting pushed around by Biff his whole life. He's always unsure of himself and ready to give up his ambitions because he can't stand even the thought of rejection.

!!The Animated Series:
* HilariousInHindsight: One episode has Marty go by alias of Jimmy Olsen. David Kaufman, who voices Marty, would later go on to voice ComicBook/JimmyOlsen in [[WesternAnimation/SupermanTheAnimatedSeries several]] [[WesternAnimation/JusticeLeagueDoom animated]] [[WesternAnimation/SupermanVsTheElite productions]].
** Years after playing Marty, Kaufman voiced [[Film/StuartLittle another Michael J. Fox character]] for a [[RecycledTheSeries cartoon adaptation]].
* RescuedFromTheScrappyHeap: Clara, for some of her detractors.
* RetroactiveRecognition: Creator/JoshKeaton voiced Jules.

!!The [[Pinball/BackToTheFuture Pinball Machine]]:
* TheProblemWithLicensedGames: Instead of doing anything interesting with time travel, time paradoxes, hoverboards, or getting the [=DeLorean=] up to 88 MPH, Creator/DataEastPinball slapped ''BTTF'' artwork on a generic pinball table loaded with {{Spelling Bonus}}es, threw in a few songs from Music/HueyLewisAndTheNews and Music/ZZTop, then cashed the checks. No wonder MichaelJFox refused to license his likeliness for the game.
* TheyWastedAPerfectlyGoodPlot

!!Telltale Game:
* AccidentalAesop: The ending of Episode 5 is sort of the logical conclusion to the entire series and films. [[spoiler: Screwing around with the timeline keeps fucking things up til you have ''three'' older Marty's begging young Marty for help, all from different timelines. At that point, Doc just shrugs and tells Marty to ignore them. ''Now'' is important.]]
** It's actually brought up several times throughout all five episodes.
* BrokenBase: There is a certain friction that occurs between those who are longtime fans of the ''Back to the Future'' franchise and those who are longtime fans of the Telltale Games company.
* EvilIsSexy: Young Edna.
* FanonDiscontinuity: To main die-hard fans of the original trilogy, this game might as well not exist. Less die-hard fans are fine with it, though. Being an example of NoProblemWithLicensedGames (and getting many of the original actors back) really helps. It's also the first thing in the series to really utilize Jennifer as a character, and both Edna and Trixie serve to balance out the series' mostly male-dominated cast.
** Telltale has stated that the game doesn't necessarily have to be considered canon.
* JerkassWoobie: Even after everything, it's hard not to feel kinda bad for [[spoiler: 1931!Edna]] when Marty breaks [[spoiler: her up with Emmett]].
** And then [[spoiler:Crazy Mary!Edna]]. HumorousInsanity aside, it's hard not to pity exactly what TheSlowPath, guilt, and loneliness have done to her.
* [[JustHereForGodzilla Just Here for the Plot]]: Many non-gamers have taken interest in the game strictly for the ''Back to the Future'' story line -- much to the chagrin of the more avid gamers who are, overall, disappointed with the game play of the series.
* MagnificentBastard: Marty shapes up into a heroic version through the game.
* MoralEventHorizon: (Episode 3) [[spoiler: Edna Strickland]] could have passed for an [[TheScrappy extremely obnoxious]] WellIntentionedExtremist until [[spoiler:she has her husband, Citizen Brown, tortured and brainwashed at the end of Episode 3]].
* PlayerPunch: [[spoiler: Citizen Brown's possible FaceHeelTurn.]]
** [[spoiler: Seeing Citizen Brown die after being ran over by Edna.]]
* RescuedFromTheScrappyHeap: Jennifer stops being a ShallowLoveInterest and gains some actual personality traits.
* TheScrappy: Edna Strickland, though this is intentional.
* TheWoobie: The Citizen Brown timeline in Episode 3. Everyone seems on the verge of a nervous crackup due to the {{Dystopia}} of alternate Hill Valley, Marty seems like he's panicking about 86% of the time, and the only halfway ''normal'' person is a {{Delinquent}} who would probably be a child psychologist's field day. [[spoiler: Even Brown himself comes off as a TragicHero.]]
