History YMMV / XmenDaysOfFuturepast

** Bolivar Trask's [[AbilityOverAppearance dwarfism]] in this film has cast his antagonism of the mutant race in this light for some viewers. He either admires mutants and just sees them as a means to an end for protecting Earth, or he hates that he was born with a perfectly ordinary and useless mutation while all other mutants win some form of SuperPowerLottery. Note that this is an interpretation Creator/PeterDinklage and Creator/BryanSinger disagree on; Singer brought the theory up as a possibility, while Dinklage was strongly opposed (the man has made [[AbilityOverAppearance "not playing a dwarf"]] his life's ambition). And to the movie's credit, no one ever really mentions or even seems to ''notice'' that Trask is a dwarf (except maybe that one senator during the first congress hearing who subtly compares him to a Neanderthal). If he were played by a non-dwarf actor, almost nothing would need to be changed.

** In ''The Rogue Cut'', [[spoiler: Rogue has spent years being experimented on to further the Sentinel Program and the moment she is freed doesn't mean she's any better off. Especially since her ex-boyfriend is killed in front of her eyes. Also, watch her face when one of the sentinels bursts into the monastery, ready to fire. She knows it is the end.]]

** In the stinger, [[spoiler:Apocalypse's pyramid-forming]] looks a bit on the ConspicuousCG side.

* OvershadowedByControversy: {{Inverted}}, oddly enough. The critical and commercial success of the film was able to overshadow director Bryan Singer's sexual assault allegations (which were subsequently dismissed anyways... though not forever).

* FunnyAneurysmMoment: The [[BittersweetEnding bittersweet but somewhat hopeful endings]] of ''X-Men United'' and ''The Last Stand'' are now significantly less so due to the (non-[[CosmicRetcon cosmic]]) retcon in this movie, which essentially reveals that the future of relations between mutants and the rest of humanity was ''always'' doomed, due to events set in motion decades before the first movie.
** Heck, the entire movie becomes this with the reveal that [[spoiler: mutant-kind has been dying out]] in ''Film/{{Logan}}'' - though WordOfGod has it that that was just a separate BadFuture of its own.

** Professor X reassuring Beast in ''Film/XMenTheLastStand'' that "You are always welcome here. You are a part of this place" becomes that much sweeter when you take into account their close relationship in this movie.
** The [[Film/XMen1 first movie]] has Professor X telling Logan, "I give you my word that I will use all my power to help you piece together what you've lost, and what you're looking for." Wolverine doesn't know it yet, but what he's ''truly'' looking for is ''right in front of him''. As ''Film/XMenDaysOfFuturePast'' demonstrates, Xavier is the person who gives meaning to Logan's existence; the "master" to his "samurai," so to speak. This is especially true in the [[spoiler:AlternateTimeline, where Wolverine has settled down as a history teacher at Charles' school, and is genuinely happy--probably the happiest we've seen him in the entire film franchise]]. ''Days of Future Past'' makes it clear that it's Xavier--and not Jean Grey, as ''Film/TheWolverine'' [[UnreliableExpositor might have you believe]]--who is the most significant figure in Logan's life during his post-amnesia years.

* EpilepticTrees: With Disney's purchase of Fox, there has been some speculation that the {{retcon}}s introduced in the movie will be ''re''-retconned externally to make the series canon with the Franchise/MarvelCinematicUniverse.

* EnsembleDarkhorse:
** Even with all the FandomRivalry shenanigans and costume grievances over Quicksilver, he ends up stealing the show when he's on screen.
** Blink is one of the highlights of the movie because of her unique look and creative uses of her power in the action scenes. Most fans predicted this, since the character's comic counterpart is already a pretty big fan-favorite, and for the exact same reasons, no less.

* CreepyAwesome: TheStinger, where [[spoiler: Apocalypse stands over a crowd of people chanting his [real] name, while he telekinetically constructs a pyramid in about 15 seconds.]]

*** A factor for some is the non-cosmic retcon caused by the "Past" being 1973, instead of our present as in the comic and previous adaptations, which will make it harder for people to rewatch any of the first three movies without thinking, "It doesn't matter who wins here, the Earth has been doomed for over thirty years anyway."

*** It's also worth noting that Wolverine's death in the original comic (where a Sentinel [[StrippedToTheBone vaporizes all but his Adamantium skeleton]] with a single blast) is arguably the [[SignatureScene most memorable scene]] in the story. His taking over Kitty's role makes it impossible that the scene could be in the movie.

* UnfortunateImplications: It's [[http://spoonyexperiment.com/vlogs/spoony-april-watch-x-men-days-of-future-past/ been suggested]] that the casting of Creator/PeterDinklage as Bolivar Trask was an attempt to ''invoke'' unfortunate implications; by insinuating that his hatred of mutants is due to bitterness that he has a genetic mutation that gives him dwarfism rather than being telepathic or able to manipulate metal. Though he admitted it was on the edge of bad taste, [[WebVideo/TheSpoonyExperiment Spoony]] felt the implication added depth to the character. It should also be noted that Peter Dinklage disagrees with this interpretation (quite naturally, as one of the greatest challenges for dwarf actors is finding characters who are ''not'' defined by their dwarfism.)

** Xavier's fans were extremely annoyed when he was given the AngstWhatAngst treatment in ''Film/XMenFirstClass'' after the trauma he had experienced during the climax, so ''Days of Future Past'' rectifies this by revealing that Charles had bottled up his emotions as a coping mechanism, but the damn he had placed over his pain finally bursts when he's [[DespairEventHorizon forced to close his school]] after a single semester. Moreover, ''First Class'' was heavily advertised as containing two lead characters of equal importance, but in truth, Magneto was the main protagonist, so those who liked Xavier more were understandably disappointed. Creator/BryanSinger, a Professor X fanboy, balances out this inequality by giving the younger Charles the most CharacterDevelopment in the sequel.

* OlderThanTheyThink: This film introduced mainstream audiences to the character of Blink, whose power is essentially to create portals. This resulted in many people saying the character must've been inspired by the video game Portal, even though the character Blink predates that game by over a ''decade''.

* OvershadowedByControversy: {{Inverted}}, oddly enough. The critical and commercial success of the film was able to overshadow director Bryan Singer's sexual assault allegations (which were subsequently dismissed).

** Wolverine being the one to travel back in time rather than Shadowcat, who did so in the original storyline. Part of the reason this causes backlash is that Shadowcat's role has been played by another character before, by Bishop in [[WesternAnimation/XMen the 90's cartoon]] (presumably in an attempt to capitalize on the then-recently introduced character's popularity). Not to mention the Professor more-or-less filling the role in ''WesternAnimation/WolverineAndTheXMen''.

** Did future Magneto honestly believe 70s Magneto would help Wolverine and co. and that him going rogue was unforeseen, or was it all part of his plan? Though he might not have known how his younger self would react.

* HypeBacklash: The film is hyped as being a return to form for the X-Men films, mitigating all the troubling qualities of the previous installment, and is said to be as good as the Franchise/MarvelCinematicUniverse films; in other words, it's very, very hyped up. For some, it really doesn't live up to it, especially those who still see many of the same issues as before creeping in.

** Bishop in particular. Although the NinetiesAntiHero fad burned out a long time ago, he remains a rather popular character (very much like Comicbook/{{Cable}}) and enjoys the honor of having been the character sent back in the 90's animated adaptation of the storyline ([[MythologyGag which is presumably why he appears in this film and is the first character seen using the travel]]). However, his film version lacks any meaningful background or motivations, shows a notably different personality, and barely has any lines at all. As this is the only film in the franchise to deal with one of the X-Men's many potential future timelines, many people would have wanted to see his character used for something more than being one of many [[RedShirts red shirt heroes]].

** The older Professor X reassures his younger self that empathy is "...the greatest gift we have: to bear their pain without breaking." That must have sounded like a bold statement to his 1973 self because at the time, he regarded his psychic nature as a grave weakness, but his elderly self is proven right in ''Film/XMenApocalypse''. Xavier shoulders the burden of [[spoiler:Jean Grey's distress over her telepathy, and this forges a strong father-daughter-like connection between them. Through ThePowerOfLove, he helps her to conquer her fears during the climax, and she is able to use the Phoenix Force to save his life and the world]].

** A small one, but this film explains how Hank could be Beast in ''Film/XMenFirstClass'', but appear human on TV in ''Film/{{X2| XMen United}}'', and how Xavier could have the use of his legs in ''X3'' and ''Origins''. [[note]]Except that taking the serum cancels Xaviers powers, yet in those films he walks and uses his powers at the same time. Presumably someone managed to make a version(s) of the serum without the consequences, but it was too unstable to be used consistently.[[/note]]

** There is no doubt Mystique is a heroic figure in the movie. By the '70s, she is the only one who actively works for the mutant cause and does things like rescuing Alex's unit from being experimented on by Trask. However, her assassination plan needs work. She consistently chooses to attack Trask at ''very'' high profile events like the Paris Peace Conference and the Sentinel demonstration in Washington DC, where security is typically tight and she has a higher risk of being killed and/or captured, which is exactly what happens in the original timeline when Charles Xavier isn't there to talk her out of killing Trask. Also, the fact that she's so determined even when she's flat-out told that it's going to end badly. The first attempt can be semi-justified by her having found out about her friends' deaths the night before (and therefore probably acting rashly). The second however...as the Honest Trailers puts it:

** Xavier's fans were extremely annoyed when he was given the AngstWhatAngst treatment in ''Film/XMenFirstClass'' after the trauma he had experienced during the climax, so ''Days of Future Past'' rectifies this by revealing that Charles had bottled up his emotions as a coping mechanism, but the dam he had placed over his pain finally bursts when he's [[DespairEventHorizon forced to close his school]] after a single semester.

* RescuedFromTheScrappyHeap:
** This film saved the X-Men movie franchise in the eyes of many fans after two [[Film/XMenTheLastStand underwhelming]] [[Film/XMenOriginsWolverine movies]], and [[Film/XMenFirstClass two]] [[Film/TheWolverine more]] that were better-received, but overshadowed by the success of the Franchise/MarvelCinematicUniverse (and [[FandomRivalry resented by some for not being part of it]]).
** Before the movie's release, Evan Peters' portrayal of Quicksilver was already being highly criticized for a) not being the same as Aaron Taylor-Johnson in ''Avengers: The Age of Ultron'' and b) his costume, which many called ridiculous. When the people got to see him in the film, the public's opinion of him changed radically after the [[OneSceneWonder Pentagon kitchen scene]].
