It's a little-known fact that a good scary movie can reap health benefits.
It sets heart and mind to racing (cardio!), adrenaline coursing through the veins and allows one to consume massive amounts of snacks (carbo-loading!). But, because the metabolism is revved up (see cardio, above), the body burns up the extra calories.
Finally, the lights come on and you can sit back up in your seat (good posture is so important), and you have achieved Zen. Life is good — but you never want to eat anything covered in red sauce again (reduction in appetite = weight loss!).
So you see, "The Last Exorcism" is a great way to unwind on the weekend, even if it is a rip-off of "Rosemary's Baby," "The Blair Witch Project" and of course, 1973's "The Exorcist."
This newest incarnation actually starts out fun. Cotton Marcus (Patrick Fabian) is a smug Louisiana preacher who admits his exorcisms are fakes. But he's tired of the sham, and decides to get a film crew to videotape him performing one last ritual.
