YMMV / My Hero Academia: World Heroes' Mission

• Common Knowledge: Fans tend to state Midoriya beat Flect by just punching really hard. In truth, he used One for All 100% and unleashed a constant volley of attacks to overwhelm Flect's Quirk before delivering a final, powerful attack.
• Ensemble Dark Horse:
  • He gets no speaking lines but Singaporean hero Big Red Dot is notable for his design based on the country's mascot, the Merlion, his quirk that makes him spit water from the mouth like the main Merlion statue in Singapore, and his name being a reference to the country's Affectionate Nickname of Little Red Dot. Singaporean fans love him as a respectful homage to their nation.
  • Egyptian hero Salaam has gotten some fans with his funny design - he's basically a living hieroglyph - and possesses a can-do attitude that even impresses the UA students operating in Egypt.
• Fandom Rivalry: A weird case of this within the MHA fandom. There's a notable amount of fans of the anime who blame the slight dip in quality of the 5th season on the existence of this movie, particularly since the My Hero Academia: Meta Liberation Army Arc was one of the most highly anticipated arcs fans were looking forward to getting adapted.
• Harsher in Hindsight: Midoriya's Imagine Spot of a mountain of heroes' corpses eventually come true during the Paramation Liberation War. However, while not everyone dies, named Pro Heroes were among the casualties and not just Red Shirts.
• Hilarious in Hindsight: The "Wanted for Mass Murder" scene has been a subject of immediate ridicule. Then came the manga with the Tartarus Escapees arc, where due to his gradual mental breakdown coupled with his increasingly tattered costume Deku gained an intimidating and sometimes downright terrifying appearance which would make for a much more credible suspect.
• Moral Event Horizon: To make it perfectly clear Flect Turn and by extension Humarize are not to be sympathized with, the organization's first scenes have them activating a Trigger Bomb in a populated city, resulting in several innocent citizens' deaths just because they have a Quirk. Not only does this event endanger the lives of several Quirkless people, Humarise responds to this with utter indifference. The fact that they plan to repeat this mass murder throughout the world is what drives the plot.
  • Flect goes further into this when it's revealed he murdered Eddie Soul by blackmailing him into making the Trigger bombs by threatening to kill his children, including the two quirkless younger siblings, showing himself as an utter hypocrite who doesn't give a damn about killing quirkless people to achieve his goals.
• Narm:
  • Ever since the first promotional clip, the scene of the newscast of Deku wanted for mass murder has been prominently featured. It's intended as some shocking moment but falls flat due to how immediately clear it is that Deku has been framed and how not menacing his picture appears there.
  • The villainous group Humarise is pronounced exactly the same as humorize (as in, to humor someone). As a result, all the dramatic statements involving their name just ends up sounding silly.
• Nightmare Fuel: The opening scene of the movie depicts Humarise detonating a Trigger Bomb in a populated city, resulting in the near entirety of the population undergoing a simultaneous Super-Power Meltdown and leveling the entire place. And Humarise wants to pull off more of these bombings around the world simultaneously! Yikes!
• So Okay, It's Average: If they're not too bitter about the alleged drop in quality of season 5 of the anime, most fan response to the movie falls under this. While it still featured plenty of great action scenes and animation, as well as good chemistry between Deku and Rody, the movie didn't really add anything new or substantial to the franchise besides having the villain be a worldwide threat.
• They Wasted a Perfectly Good Plot:
  • Humarise’s viewpoints on Quirks positions them on the opposite end of the spectrum from the Meta Liberation Army, who, no doubt, would not take kindly to a world-spanning organization plotting mass-genocide against those possessing Meta Abilities, yet neither they nor the League of Villains are even mentioned over the course of the movie.
  • One of the reasons Rody, before meeting Izuku, dislikes heroes is that the slum where he was forced to live at with his siblings is never visited by them because there's no fame or money to be had by working there. The series has sometimes shown how similar contexts can nurture villains - Rody himself was forced into petty crime to make ends meet, but nothing more is discussed about it and Izuku has no apparent reaction or reflection to that.
  • A smaller example, but some fans have complained about how the series taking place in Japan (mostly in a school setting no less) results in a rather limited perspective on a world where 80% of humans have superpowers. The mission having established characters stationed in different countries created a rare opportunity to explore how other nations handle quirk regulation or show unique variations in hero culture. Unfortunately, the "world" aspect of the film seemingly just existed to raise the stakes and feature more of the supporting cast than the previous movies could.
