Half-Decent, but the ending is TERRIFIC

Rating: 10/10 (31 October 2009)

I had heard that Paranormal Activity was one of the scariest movies ever, so going in my expectations were high. And for the most part, they weren't met. It wasn't boring at all, and I enjoyed it thoroughly, but most of the movie is only slightly disconcerting and not at all frightening. It remains engaging throughout, just not scary.
HOWEVER there are some scenes (three or four) interspersed through it which are positively alarming. The ending is by far the scariest ending I've ever seen to a horror movie. By far. For me, the ending brought the movie from a B to an A.
The Blair Witch Project is highly comparable to this movie, and if you like one then it's probable you'll like the other.
