Great idea, I really liked it at first, full of mystery and an occult. But then it got a little bit... Let's say, confusing. Some parts didn't make sense, they did not bother to explain it or to "develop" a story a little bit. The ending was somehow disappointing. Too bad, since I like these types of movies, and like I sad, it had such a potential. Still it is not a total waste of time, actors are good, there is an eerie atmosphere throughout the movie, etc. It is not bad, just not very good :) if that makes sense :)
