I have watched all types of horror movies for over 30 years, and I can say that this movie is something special. Very scary, very suspenseful, very terrifying! I actually was seeing the images when I laid down to go to sleep! The scariest movie of all time is, of course, The Exorcist, however, Paranormal Activity is definitely in the top ten. Unique, engaging, and riveting. I can't stop thinking about this movie! I really want to see it again. I got chills several times. Not for those easily spooked, but well worth the hype and wait. I loved it. A+
