Without spoiling anything, this movie is not simply about "spirits and ghosts." The entity in this film is demonic. There were several scenes that not only kept me on the edge of my seat, but also made me come up out of it. For those who do not believe in the paranormal and are looking for a realistic psychological thriller, then this movie does not disappoint. However, for those who become paranoid at the slightest little bump in the night, I suggest that you do not see this movie alone and be prepared to have someone stay the night with you. It is creepy, and it will freak you out, though it has its funny moments. Wish I could write more, but this site has a character limit.
