As recommended by a friend, I really believed this movie would fail to exhibit the natural scare effects, some sort of less appealing "Blair With Project" in a sense. However, with the movies constant plot, be it based on true events, let alone be actual clips from peoples lives, this delivered 100%. The movie builds the anticipation and scare, increasing over and over, letting some relax but, lingers even after the movie is done. The night itself becomes one terrifying encounter a person goes through after watching Paranormal Activity, fear of sounds and shapes, odd shadows, the works of a scary movie. To not watch this, is insane.
