Now my opinion of this film varies; firstly from my initial opinion of the film before watching it, based on reviews and my expectations etc. From what i'd heard it was fairly good and considerably scarier than both Paranormal Activity and insidious, which in retrospect i can kind of agree with.
The quality of the horror was good; the face of the demon guy (i guess that's what he is, i don't remember his name, he reminded me a lot of Jim Root's slipknot mask.... anyone?)
But overall very good movie, pretty good cast, there were some neat scares in the movie and the plot was fairly original. Won't hit my top 10 favourite movies ever, which i may actually make at some point, but yeah solid movie, definitely get some scares out of this one, check it out.
