In the trailer, the contorted spook face floating over the bed just looks desperate and derivative. Linking it to the Amityville Hogwash doesn't make it more compelling for me (although Amityville 1979 was a bit creepy).
Scarier than all the Paranormal Activity movies combined? Should that impress me? The narrative scenes of Paranormal 1 neutered the nightvision scenes. Paranormal 3 was embarrassing.
Probably still watch it. Might have a few creepy moments.
