I’d hoped for teeth clenching, jumping and being slightly grossed out. I wasn’t disappointed with the effects but that's pretty much what the movie was. There weren’t points that made me cringe or jump. For the thrill-factor the movie fell short of my expectations. Still, there were some pretty horrific scenes which made up for much, particularly with the 3D display. As a slasher flick I'd give this 3 stars but 2 main points took away from it for me - the awkward attempts at plot twists and the acting of Jensen Ackles. When trying to look angry he tried too hard which looked silly and his attempt at shock/fear made him look like his brain runs slower than a frontal-lobotomy recipient. If going… see this in 3D so you can enjoy that much.
