It is not deep, but it is fun to watch. It does have a bit more of an edge to it than other similar films.

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

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