Go see it and you'll be glad that you did. This movie in my opinion is on the same level as the Exorsist, but I enjoyed the story here a lot more. There's just nothing like a movie about a seemingly normal family following their dream of owning a beautiful home in the country only to find out that the house is possessed by demons and that you can't leave because they have attached themselves to you and will follow you. Scary stuff for sure. Now you throw in the fact this is all based on true events and it makes it all that much better. Its been a long time since we've seen a horror film of this caliber come out of Hollywood.
I can live without a good story of demonic possession, tyvm!
