I went into this expecting a stupid exorcist rip off.Not at all the case. The story does revolve around an exorcism that already happened and everything that ensued from it and what led up to it.A lot of it told in flashbacks but plenty going on in the present too.The story is told at a nice quick pace and keeps you interested.A lot going on here and the acting is pretty good too except for the mother(but we can let that slide).All in all,a good solid movie. I definitely recommend!
