I'm STILL sleeping with the lights on after watching this movie over the weekend. Be prepared to laugh, scream, and be scared. There are some authentically funny parts in the film that are meant for you to laugh. Then there are the parts in the film that make you groan in fear. THE scariest film I have EVER seen in my life and I am a horror-film fanatic. Word of advice: in order for this film to have an effect on you, you have to believe in paranormal activity. If not, this movie's premise will fly right over your head and you'll probably HATE it.
