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 film may be flawed, but its message is not.

The best films of this genre always show a path and provide a takeaway for being a better person.

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