Reason 3: Paranormal Activity 3
This one IMO is the best in the franchise. And I wish I could put into words how creative this movie was in creating the scares. Even when you knew the jump scenes were coming you couldn’t help it. Attaching the camera to the rotating fan was genius, among other things. It was an extremely entertaining movie, but i’ll say this about it for doubters. The scares and fears it uses really works on the folks who have some sort belief in ghosts and demons.
