I'll tell you why so serious

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.
