The premise of Midoriya being frame for something he never did and being hunted down is an interesting premise. This could've made for an interesting conflict where he is getting hunted down by heroes or his classmates. Maybe there could be an interesting detective story to it with Midoriya having to investigate who the real culprit is.
It is a shame this movie does absolutely nothing with it and waste the idea of it. It's also ridiculous that there is a villainous group that is threatening on a world scale. They are somehow more threatening than the actual main villain of the manga. There isn't a fight scene that is as cool as the previous movie which is a shame.
What this movie does do better is having an actual interesting support character in Rody. He is more interesting than most of Class 1-A. His relationship with Deku is the most enjoyable aspect of the film and is the one thing that makes this movie fun to watch.
Overall, watch it for Rody!
