2nd season: 8/10
3rd season: 9/10
4th season: 7/10
5th season: 7/10
1st movie: 9/10
2nd movie: 5/10
Futari no hero: 6/10
Ikinokore: 8/10
Sukue: 8/10
Training of the Dead: 8/10
As you can see and compare, this movie disappointed me greatly and became the worst piece of media on the BnHA franchise so far as I've given this a 4/10.
Visuals: the animation is pleasant to watch most of the times but it's so inconsistent that often broke my immersion.
Sound: nothing too outstanding. I've heard more emotions coming from these characters in the regular seasons that in this movie.
Story and characters:
1) the biggest flaw for me was pacing. We're talking about a movie that lasts almost 2 hours and 45 minutes in, I almost fell alseep. We are introduced very early on to a new character that will occupy the screentime for ages throughout the movie but there's no charisma to him. His screentime could've been cut short (and it should!) and the story would still be the same.
2) Not only that, but I get the most joy out of this franchise when I get to watch a bunch of heroes showing off their quirks and developing themselves as indivuals and unfortunately this movie in my opinion focuses way too much on Deku. This is what made me fall in love with the franchise, how every character is very important and doesn't exist just to feed the main character.
3) Bakugou, Deku and Shoto don't act like they normally would. Deku becomes dumber for whatever reason, Shoto forgets that ice is frozen water and Bakugou had no intensity to his attitude.
Watch this is if you're a BnHA super fan of course but prepare to be disappointed or watch this in 2x speed or something so it's less painful.
