As scary and well-made a horror film as I've seen for its first two-thirds. Not Rosemary's Baby exactly, but definitely in The Changeling territory. Compelling and unnerving, as in "I might turn this off" unnerving. The last third is more akin to a Mick Garris television adaptation of a recent Stephen King novel. It's a huge drop-down but I kind of like Mick Garris TV movies so, all in all, a big thumbs up from me.
