Let me start by saying that the first movie was one of the scariest movies I've ever seen. That movie messed my head up big time and I had a hard time sleeping for a while after it. I actually insisted on seeing this during the day just in case. It was nowhere near as straight up scary but it was still plenty creepy and very watchable for a horror movie. This was more about violence/murder than the first one was. They just started right up and sent straight through the really short run time.
I would definitely recommend horror fans checking this out. It's a textbook creepy stalker movie.
