Query: Great scary movie.

This was a very creepy, very well done movie, I was truly scared and I watch a lot of scary movies. This film gave me the true sense of fear that I felt while watching such films as The Blair Witch Project and the Exorcist. This movie was way better and scarier than I ever imagined, these films are truly the scariest films you can watch, true human fear with limited effects. Very well done, truly scary, and one of those great films you can't watch in the dark.
