I'm a big fan of found footage horror, and this one is incredibly successful at it. It's a slow build, as they usually are, but it all serves to build up the tension and lay the framework for the climax.

The cast of characters was set up extremely well in the beginning. They all had distinct and seperate personalities that were at once believable and easily identifiable as you watched them continue through the film. They did a good job in setting up the dynamics through action and short dialogue to pull you into the group.

The setting is nothing unusual for a film like this, I've seen asylum movies before, but it was used very effectively. The plot delivers some interesting twists and turns from what you would generally expect from this sort of movie though and for that, I applaud it.

On top of it all, I think it was acted incredibly well. The characters were all so believable because the actors really did a great job. I believed them every step of the way.

Overall, very enjoyable.
