The Human Centipede is the nastiest film I have ever seen. It out ranks all of the Saw movies combined. I watched it about 3 years ago and I am still haunted by the awful images! It was the butt sowed to the mouth parts and the pooping parts that really haunt me. I love gorey movies, but I seriously should have never watched that movie. I still can't look at Rottweilers without cringing and saying a prayer.
