Hearing about this movie from critics as one of the Summer's best sleepers I had to find out for myself.. and I was literally "blown away!" EASILY this year's best movie it had me squirming in my seat,half closing my eyes and ears, screaming out on occasion.. absolutely a tremendously entertaining and well made movie! It's been years since I had a horror movie (Insidious and Paranormal) affected me like that.. Edge of your seat,hold your breath type of terror..
