Besides the bad acting from a few of the actors, the movie was "eh." It started off like any normal horror flick with a few intense sequences and creepy camera angles. But after about 25 minutes, you just stop caring about the characters. They don't react the way a normal person in their situation would and it was kind of annoying.
You know those movies where you expect someone to react in a way and they do the complete opposite? That's kind of how this movie was; just OK.
The makeup team did a great job with the character Emily; she didn't look like the same person by the end of the film.
Overall, this movie could have been a lot better if they worked with the story a little more and had better direction given to the main actor and priest. Other than that, Emily's character was done well.
