No cheap scares. Generally scary and has a great story!

Rating: 10/10 (25 December 2014)

I don't get the hate from all the reviewers. I felt that this was actually scary. It was great at building suspense, and there were no cheap jump scares. While the kid was a bit annoying at the beginning, it all made sense in the end. Everything made sense and made the movie that much better.
Spoiler below The monster was the representation of the part of the mom, inner demon, that hated her son because part of her thinks he's the reason the dad died. She was also abusing him before the beginning of the movie (hence all the various weapons the son had). She created the book, as you could see when you see the ink on her hands when she goes to the police station, to separate the part that hated him as a monster so the son could still love the mom. The ending was her coming to terms with her inner demon by visiting the basement where all the dad's stuff was instead of ignoring and suppressing it.
