I read a little about this movie before seeing it and from most of what I read it seemed pretty positive. It's an underrated supernatural film in my opinion. The story is basically about these priests who are murdered by a demon who makes them sin then kills them. Later in the movie it's revealed that a single priest would be chosen to battle the demon known as the Unholy.

The film has some good creepy moments and maybe a scare or two, but it does fall apart a bit towards the end compared to the pace of the rest of the movie. It seemed out of place, like it was a bit rushed and I think it would have been better if we didn't see the demon the way we did. They ended up showing the whole demon and it's somewhat silly looking.
