I did not like the 3rd MHA movie. The whole hype behind the film was Deku Bakugo and Shoto in those neat stealth suits. Which were used for one scene at the very beginning. The middle of the dragged on for what felt like forever and lost of the other classmates 5hat were in the movie had painfully little screentime. The whole enemy cult being built on hypocrisy took alot of its potential drama away from it to devolve into superpower fights.
These types of films do tend to be mostly spectical and little substance, only two films that I can really think of, are apart of their respected canon stories and are pretty desent:
Dragonball Super Brolly & Demon Slayer Mugan Train, thou the Demon Slayer film is pretty much just one chunk of a much larger story, while the DBS, in terms of anime, its pretty much stalled as they are waiting on the manga, thou they got a new film coming out, this year, but that just looks terrible as it completely CGI! While I can think of another pair of films that are apart of their respected universes, they just feel completely shallow and devoid of heart and pasion, those films would be the Sailor Moon Crystal ones that came out resently, while they are adaptions of the manga, the way they are presented is just kind of feeling as if there was no real heart or pasion and its just a shiny cash grab, thou this is merely my view.
