Deliver Us from Evil

If you wanna compare this movie with another movie, you could compare it with the classic "Straw Dogs" (Dustin Hoffman, Directed by Sam Peckinpah)! And it plays in that League, because it is really good, acting-wise and story-wise!

Having said that, of course if you don't know what to expect, you might be disappointed, as can be seen, by another reviewer on this site. Of course he is just warning other people, that might have the same problem he had, just don't let that cloud you own judgement and if you can go and watch this little dark thriller, with more humanity than quite a few other movies with similar stories.
