The realism of this movie brought me much fright. I found myself morbidly looking forward to each night just to see how much more the entity was going to push the couple.
If you have ever gotten scared at night alone in bed for whatever reason---ghost, demon, home invader, then this movie will take it to an entirely new level for you.
With that said, if you dont believe in demons, this might not be the movie for you. And when I say demons I mean a demonic force driven to terrorize through terrifying, messed up psychological ways.
