I usually dont like to see horror movies, but the only ones I do like are the ones that creep under my skin, the ones where it's not the monster itself, but the fear OF some creepy monster that unnerves. THIS is such a movie.

The good: I must applaud the contineous unnerving vibe this movie unleashed upon me as a viewer. It really was quite effective at creating a creepy, maniacal vibe.

More good: beautiful photography, with (fortunately) no silly CGI tricks, but instead rather real looking special effects that look quite daunting.

The actors arent terrific, but the one leading actress is certainly very good at her role of someone who gets possesed.

Probably not suited for the more casual viewer, because this movie is not a comical horror movie, but a rather nasty and creepy one, but THAT is it's undeniable power!
