I've never jumped so hard watching a horror film in my entire life! Yes, the first part of the movie is a little slow, but it gives you a chance to see the characters and get a sense of their relationship. By the end of the film, everything has gone to @$#&! I love horror films, and never have I hated the idea to go home alone after a watching a "scary movie". Get ready to raise your voice, because this movie will have you screaming!
