Some of the comments on [[https://goo.gl/dn55HP twitter]] or [[https://goo.gl/Dc5FKb weibo]] remaining since May 2018 are pretty telling. The directors' page on Wikipedia has been repeatedly vandalized, with "murderers" being added to their occupation list. Thousands of viewers in China vowed to stop watching Marvel movies altogether if Loki is gone for good, fans across Russia were attaching hand-made drawings of Loki to the ''Infinity War'' official posters in the movie theaters (he was missing from all of them), and there was an abundance of implausible theories of how HesJustHiding. Some of those theories would be vindicated in Loki's own [[Series/Loki2021 spin-off show]], which has an episode featuring an OlderAndWiser Loki who really did fake his death.

** Some fans agree with Thanos' perception on universal overpopulation and his goal of wiping out half of the universe, while forgetting that planets like Titan aren't well developed enough to handle huge growing populations like Earth can, and that Earth is currently having a decline in fertility rates and overpopulation isn't really much of a current issue that Thanos builds it up to be in Earth's case. [[spoiler: In fact, with how much that ''Endgame'' proves how wrong Thanos' methods were and how he doesn't seem to do any research on how Earth manages to survive with such a population that Titan can't since he's so invested in his goals makes Thanos look like an idiot with outdated beliefs, especially since his 2014 counterpart in ''Endgame'' didn't even check to see if his plan actually helped Earth.]] Furthermore, there were any number of alternate solutions he could have tried with the Infinity Stones besides simply killing half the universe at random (which isn't even a ''lasting'' solution, and realistically kills ''more'' than half the universe by collateral damage): for example, he could have made the entire universe ''wiser'' so its people would pursue more sustainable practices. This was even entered into canon in ''WesternAnimation/WhatIf2021'', which shows that if he encountered someone as mature and reasonable as T'Challa rather than Peter Quill, he could easily be talked out of his plan before he truly set out to accomplish it.
* MisBlamed: Those who didn't like Gamora's death at Thanos's hands tend to blame the writers of this film for shoehorning her death into this film, despite it immediately being undone in the sequel. In truth, Creator/JamesGunn had considered killing off Gamora back in ''Film/GuardiansOfTheGalaxyVol2'', and approved of her death in this film.

** Also, for a specific example: the fake-Thanos dying on Knowhere. No-one would really think that the film's BigBad would die ''that'' early and certainly not ''that'' easily. The scene itself doesn't go along with it much either, as while Gamora instinctively reacts as if he really is dead, Quill's reaction is a quiet "That was easy..." as if he can't believe it's really over either. [[spoiler: Ironically, ''Film/AvengersEndgame'' actually kills Thanos ''within the first ten minutes'' with even ''less'' of a fight... [[TimeTravel at first, anyway]].]]

** It's also suspected that Gamora is still alive inside the Soul Stone, which is actually the child Gamora who Thanos sees at the end, and will be freed in the sequel. Likewise it's been theorized that many of the dead characters are actually inside the Soul Stone and could be freed, since several such "dead" characters have additional movies confirmed in the future. [[spoiler: {{Jossed}} in ''Film/AvengersEndgame'' where it's confirmed that there is no saving someone who was sacrificed for the Soul Stone.]]

*** Also, Rocket tells Quill "You're one sandwich away from fat!" And then in ''Film/AvengersEndgame'', Thor is the fat one, while Quill remains the fit one!

** Long before their daughter is born, Tony discusses a dream he had with Pepper about having a dream about having a boy named Morgan, which Pepper dismisses. With ''Film/DoctorStrangeInTheMultiverseOfMadness'' revealing that dreams are actually a connection one makes to an alternate universe, this indicates that there really is a universe where Morgan was born male.

** Strange's declaration that he would be willing to sacrifice both Tony and Peter for the sake of the universe was already harsh enough after Tony's death in this film's sequel. As of ''Film/SpiderManNoWayHome'', [[spoiler:Strange ends up having to erase everyone's memory of Peter to prevent the universe from collapsing in on itself, thus forcing Peter to lose everything he ever had in his life.]]

** Thor lampshades that he's seen Loki [[spoiler:die before, and each time it's been a lie, but feels by instinct that this time his brother is gone for good]]. He knows logically that [[spoiler:Loki would have enough self-preservation to rouse himself the minute Thor was left to die and drift in space]]. A later spinoff, [[spoiler: ''Series/Loki2021'' reveals that ''one'' version of Loki took this route, faking his death and exiling himself on a distant planet to wait out the war. Even worse, the guilt eventually caught up to him, but he was never able to reconcile with Thor because the minute he tried to return to space, the TVA caught up with him and sent him to the Void]]. 
** Wanda and Vision's conversation before Corvus Glaive and Proxima Midnight ambush them in Scotland become this when you realize [[spoiler:[[Series/WandaVision Vision was about to tell Wanda about the property he'd bought for them in Westview]]]]. Furthermore, Wanda having to sacrifice Vision for nothing is also this, [[spoiler:as it is one of the factors that lead to her actions during ''Series/WandaVision'' and ''Film/DoctorStrangeInTheMultiverseOfMadness''. ''Multiverse of Madness'' also reveals that, despite accepting that Vision is dead, the futility of his sacrifice is still a sore spot for her.]]

* AngstAversion: Most of the critical and fan response has been positive, but a number of reviews have opined that the movie often gets overwhelming and excessively depressing at times, such as the massacre of many Asgardian refugees, the deaths of Loki and Gamora, and the outright DownerEnding. This ended up being a source of some controversy in South Korea since, in a rather bad case of Woolseyism, [[WhamLine Strange's line]] of [[RayOfHopeEnding "We're in the endgame now"]] is mistranslated/subtitled as [[DownerEnding "We're doomed"]], effectively killing a good portion of the audience's perception of the movie and the future of the MCU as a whole.

* Retroactive Recognition: Ariana Greenblatt as Young Gamora.

* [[EpilepticTrees/AvengersInfinityWar Epileptic Trees]]

* EvilIsSexy:
** Thanos fits the tall and muscular {{hunk}}y mold (or even a hairless example of TheBear), which shows in [[SleevesAreForWimps his clothes of choice]]. He also has a deep, husky voice that sounds very commanding.
** Proxima Midnight for being [[StatuesqueStunner muscular, tall, and beautiful]].
