good back-story, and good acting

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
