I watched this film and it had me glued from the onset.The suspense is excellent and the acting is superb.The young girl plays an exceptionally good part at being spooky without even speaking.BUT,for me personally,I like a film with an understood ending. Young girl sells soul,kills herself then the story goes South from there. The Sister plays no relevant part although the acting is very good and the "Demon" itself is played to perfection. There is no explanation at the end,it's not even a case of leaving you guessing,...it just spoils the film as it had all the hallmarks of a truly memorable Horror but failed miserable at the end.If you can cope with loose ends and like "momentary" thrills then this is for you.
