Lack of good storyline.

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.

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

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
