I'll get straight to the point. What is good about this film: an interesting plot - builds up suspension through the story rather than image, and......that is it. It could have made more sense if the director and his crew actually treated us to the real Polish countryside which I suspect they did not. Moreover 'Polish' folks are not Polish, some of them did not learn to speak their parts too well either. I mean seriously, how much more money would they have to spend to make it more authentic? In my opinion it took away the quality this film could otherwise have. Also that bit where the 'main priest' talks a lot while sacrificing the scapegoat (possessed). He makes a contribution to the Christian God according to the prayer he utters (literally Lord's Prayer). Perhaps something more original would add more suspension? On the other hand screen-writer's choice might have been deliberate, for example, to demonise Christian faith a little etc. Overall watchable but some wasted potential.
