Okay, these days "based on a true story" seems to mean nothing more than it's not an animated film. But, I find possession stories to be scary no matter what they are based on. And since it's about little girl I can relate to it, having an 8 yr old daughter. And I think that'll make it that much more scary whick makes me want to see it more.
