No offense, I would NOT recommend watching this at movie theaters, however I'd recommend watching this at home as you can pause or skip any scenes you do not like.
*SPOILER* (Do not read past this if you don't want spoilers)
Not even exaggerating or being a hater 80% of the movie was just straight up fighting over 1 girl and there was basically no storyline until the very end. I got bored and zoned out half of the movie, the best part was literally the ending of the movie.
+ Some of the scenes feel copyrighted/ inspired by the anime "Black Clover" because in Black Clover they have this scene towards the last 2 seasons where they are teleported to a dungeon in the middle of the sky to fight a bunch of people and there was also another scene but I completely forgot which one it was because I got so bored I forgot.
Overall/ Recomendation: Unless you are a HUUGE MHA fan do not watch this at the movies, watch this at home.
