Not a horror flick by any means, so don't go into it thinking that, it's a action flick with zombies as it's background. It has its regular tropes, and I was able to tell what was going to happen well before it happened, but that's not a critique on it.
At first I had my reservation about a heist/zombie flick, but they make it work. So I was happily surprised.
What gets me is:
SPOILERS:
The obvious action from a female character that leads to the demise of two other characters. If it wasn't for her, those two would have lived, yeah narratively that makes little sense, but to have them die indirectly because of such a stupid decision always bothers me.
