Man the real doll is not near as fucking creepy as the doll in that trailer. The real doll could be slightly cute if not for the paranormal background.I think Ouija might be cool. There haven't been many movies that focused on a Ouija board so this'll be nice and refreshing. As for Annabelle, here's the real story.

The Warrens are the people who were in The Conjuring. Real people who did real paranormal investigations.
