I just finished watching this movie and it was absolutely HILARIOUS. It reminded me of Zombieland and Shaun of the dead and Evil Dead mixed together. It's genre is Comedy + horror but it's mostly comedy. http://www.imdb.com/title/tt1465522/
Oh wow, I just finished watching the trailer. I'm a fan of Tyler Labine and Alan Tudyk to begin with, but this movie seems hilarious. A little grotesque, but unusually funny.
I was really surprised after watching this movie. It was great and I will definetly rewatch it in the future. At first it just looked like a crappy "Scary Movie" type film.
