If you haven't seen the trailer yet, DON'T! I'm disappointed that the trailer gives away some of the best parts of the movie, but the movie is still an absolute must see! Beginning starts a little slow and if you're easily prone to motion sickness, don't sit in the front! Most of the shaky camera filming goes away 1/5 of the way through the movie. Where usually I will jump and give a little yelp at several scenes in most horror movies, this one had me and most of the entire audience giving actual screams!! The ending was fantastic and I drove home constantly looking over my shoulder with almost a dread of what could be back there. ABSOLUTE MUST SEE!!!
