My Hero Academia: World Heroes Mission Review - 8 Ups & 2 Downs
5. Up: Characters And Relationships
The benefit of having fewer characters to focus on means that relationships either build naturally, like with Deku and Rody, or feel natural as established, like Shouto and Bakugou.
One thing this film isn't short on is chemistry. There's no need to establish Shouto, Bakugou and Deku in any clunky introductions, and the film does absolutely none of that. In action scenes, it shows how in sync all the characters are both with their Quirks and how they work together and around each other.
In dialogue, their personalities are clear from the get-go and reflect their strange and dynamic friendship. Their trust is established so quickly and thoroughly that when Deku is separated from his friends, it's not hard to accept them having the same end goal and understanding each other's motivations despite limited communication.
Most of the film's runtime is focused on the relationship between Rody and Deku, which feels remarkably natural. Their personalities are just different enough to have friction, but in a way that just makes their interactions more fun to watch, rather than setting up needless drama.
Their chemistry is the strongest in the film, which helps its quality immensely.
