I got more to say, but I think you'd just be better going into the film blind. The horror is not as hardcore as I was hoping, in fact, the film is more of a comedy, but I still enjoyed it and actually watched it twice just to pick up some of the details.
Good film, lots of awesome monsters, lightning quick pace, attractive females (especially that redhead, my god), good special effects. Check it out.
Notice the Tank and Witch from L4D? Also a Boomer in the picture below...
Wolf, ram and a heart...Wolfram & Hart?
Angry Molesting Tree and Deadites...THE EVIL DEAD.
