Deliver US From Evil
http://www.imdb.com/title/tt2377322/

The possession theme has probably outstayed its welcome as of late, but this was a nice twist on it. However, i found the story to be rather shallow and some crucial questions were left unanswered - such as why Eric Bana's character was being harassed by these otherworldly demons in the first place. The acting was good and there was just enough gore and violence to keep my sadistic side happy ,but overall it was rather disappointing as a whole. 6/10
