Wanted to like it a lot, tried to like it, couldn't like it. It starts off promising and doesn't really waste much time getting into the plot which is good but after that it just starts going downhill and by the third act it finally just loses it. Kind of the definition of a "mess" if you ask me with bland cinematography, one-note characters, and every video-game zombie cliche' there is (which is ironic because from what I hear the book's zombies were much less cliche'). The last act with the teeth-clicking zombie was laughable. Brad Pitt tries, but doesn't have much to work with, and I know it was a film he really wanted to get done but things just didn't work out this time.
I give it a C-.
