Ok, so i saw this last night.
It's a good movie. A ton of suspense. It takes a little while to get going, but once it gets going it's pretty creepy. I'll admit that even though it's a good film, i was a little disappointed. After reading the reviews and hearing the commentary from some people i know, i really thought it was going to be SCARY. It's not, well, unless you really believe in demonic spirits.
I suggest watching it, it's creepy as hell. Especially the end.
Don't half ass two things. Whole ass one thing.
