The Conjuring was great. Best horror movie to come out in years.
I recommended it to my parents and it scared the crap out of my mom.

I love everything that deals with supernatural or ghost stories but I'm also a sucker for POV movies, hence my appreciation of Grave Encounters.

Another good POV movie was The Tunnel. It's an Aussie movie so you can add it to the list. It was better than Grave Encounters.
