This movie starts off intense and maintains this intensity pretty thoroughly throughout the movie. I considered it to be a decent possession movie with occult undertones. I don't think the specifics of the specific sect of the occult portrays it accurately, but hey, it's just a movie. Also, it's not your stereotypical possession movie with the cliches of most movies pertaining to possessions. Honestly I enjoy it more than most of the possession movies I regularly see because it's not the same old cliches that tend to follow every other possession movie.
