This movie was, I and don't say this lightly, as bad, if not worse, than Indiana Jones and The Kingdom of the Crystal Skull. And do you know how BAD a movie has to be for that comparison to be acknowledged as another movie?
Credit where it's due: the first act is great. It sets up the new setting and characters well and creates a good air of suspense. It then proceeds to undermine the setting, characters and suspense it just built up for... what I will generously call indie film festival crap that wouldn't make "honourable mention".
It doesn't even have the right to think about peeking into its predecessors' shadow, it is bad, even for a zombie movie.
