Very very predictable, including the post credit scene !!!

I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

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