OK, so this is not totally totally bad and awful to get one as rating... But I also think that three would be too much...So, this gets two from me.
This is a horror movie about zombies. Or some creatures that should be zombies but they are ... whatever. Whatever is the word to describe the 'costumes' and effects. Really not convincing. Not scary at all. It has some gruesome moments but they are poorly done.
The acting is that of a high school drama meets wannabe horror actors. Very bad. No one is really convincing. And the girl which found her new best hobby - killing zombies and walking around with a gun is rather silly. The professor of those students is no comment. But I guess, it is worth watching only if you plan one day to film a horror movie to see what things ( and they are plenty!) not to do.
Cheap effects of smoke are laughable. Michael Jackson Thriller's kinda bumping into houses throughout the floor is silly. Night haunting with surprising lights in the bus is funny. So many things are just awfully done.
