For this kind of horror franchise, you can never rely on a simple clip to be a perfectly honest depiction of a film. So do not expect this to be unadulterated from what is in the actual film. They put flair and music over it to draw viewers in. As for "Paranormal Activity 3" itself, I'd normally be tempted to dismiss. In fact, I'd very much like to. But, it is directed by the two men behind "Catfish", so expect something a little more interesting than the last two films. This series, to me, has been kind of boring and uninvolving. I'm waiting to be proven wrong.
