Spoilers.
This was disappointing really. I sat in the theater bored the entire time. This felt way too familiar too (like I've seen it before) only let's throw some Satan in there. The ending made really no sense at all and yet was predictable..which I'm normally bad at predicting. It made no sense because nothing was fully tied up. Like a ball in a doll made you kill your family...like ok. And the mom was only there to make sure it happened...why? Satan obviously knows it works he don't need you. And main fbi girl sucks at being an actual fbi agent. She should have told her boss about the letter the minute she got it and then taken out of the case due to being too close to the case. Whole thing was dumb. Two stars for a little good acting on Nicholas cage part...I guess.
