Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

The movie runs out of plot and jokes well before the end of a two-hour running time, long for a light comedy.

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

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
