This genius idea combines all kinds of great things. For one, it finally brings reality television to the big screen without stretching the Paranormal Activity concept too far out of whack. But it's the celebrities that give this one it's true potential.
Ideally, we'd get to see all our favorite reality television stars as they're haunted and taken out one by one until the final contestant (probably Snooki since she looks sort of like Katie) is rescued by an exorcism performed by Dr. Drew. If that doesn't work, Sarah Palin can just shoot it to death and dine on its loins.
