You can be an arthouse flick or a slasher flick, but not both for this..

...one.

-No info on what happened like The Road didn't work here, especially for a younger audience.

-Mary just saved Nikki's life and her first act is to knock her out?

-Mary as a 'former' cannibal should have known about the trap houses. "Yo lets go inside this house and not check it out entirely until the next day" and of course thats when you find the cans.

-Punching bag mary has very bad communication skills.

-Ninja 12 yr old skank... 
Nikki deserved her slit throat for getting all the shotgun rounds from Mary.. but 'cmon

-and the one black character HAS to be "ghetto"

Cinematography was good, the rest: bullocks
