It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

This is a coming of age storyline that you've seen in one form or another for decades. It takes a truly unique voice to make yet another one worth watching.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

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