Is Eli Roth's The Last Exorcist scarier than the original Exorcist?

Spooky exorcisms are a staple among horror movies. But the latest trailer for the new Eli Roth-produced exorcism film has us wondering: Can this shaky cam "real life" film be half as frightening as the original Exorcist?

Some of the scenes in this trailer look horrifying, while others look very shaky-cam and shticky. But it is being produced by Roth, who knows how to get the audience to jump out of its seats. Here's the official synopsis:

A troubled evangelical minister agrees to let his last exorcism be filmed by a documentary crew.

In theaters August 27th.
