It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

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.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

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