There is nothing like a scary movie....and Paranormal Activity is nothing like a scary movie. People running out of the theaters horrified?? Who?? Really?!? Frankly, the ending is so obvious (and...if it is not obvious enough, the filmmakers are kind enough to beat you over the head with "clues") that anyone with a modicum of intelligence will be insulted. Save your money. Save the hour and a half of your life. What are the film critics thinking?
