It was alright.
Wouldn't watch it again.
5/10

I thought it would have been better if they'd carried on with 'crazy' storyline instead of the demonic ending. But that's just my preference.
Did the cop know the truth the whole time or just from the scene in the house at the end? It seems more like he was somehow taken over at the end to be the boy's protector, but I'm not sure about this.
