Finally someone made a movie, that is so obvious, you really wonder, how no one came up with that simple yet brilliant concept yet. All the exorcism/possession movies end, after the exorcism - whether it went right or wrong, there's not much we get after that. There have been sequels to exorcism movies of course and they show a sort of aftermath, but this is an "original", without any background as to what happened before.
Well until you watch the movie and it backtracks at certain points so we do see what has occurred. It's all done in a rather light (still vivid) fashion, that doesn't shy away from gross or graphic content. If you are into the idea, you will like what they did with it. The movie is worth it (the performances too).
