Otherwise, this movie is exactly what you'd expect for a shonen non-canon film. The first 2/3rds of the film feel like a drawn out episode with excessive amounts of flashbacks, recaps, and exposition.
The new characters introduced are adequate additions to the cast, and Dave's motivations throughout the film are rather basic, but interesting for MHA standards.
I would have liked to see less characters from class 1-A, as they made the movie feel very samey and detract from the overall experience of the film. 80% of the class being at this incredibly desirable and exclusive event stretches the suspension of disbelief to uncomfortable levels. To top it off, they have to spend a good 10-15 minutes offering explanations for why each and every character was shoehorned into the film. Paired with the prior mentioned flashbacks and recaps, it really felt like they were trying to cheap out on the budget for the first 1/3 of the film using these methods.
