The Last Exorcism is a mixed bag of frights* watered down by the script's desire to throw a few twists into the last half of the film to keep the viewer second-guessing the reality of Nell's predicament. These turns in the plot make the film feel a bit bloated and, like a fault of another smart faux doc Behind the Mask, you begin to grow distant from the main protagonist in the final act. Overall, the film tries, but it doesn't focus to try hard enough - all show and no go. It wants to make you a believer in its events, but it falters at carrying you all of the way. Worse still, the heavy metal album cover of a finale is preposterous and loud enough to almost make you forget the elements of the film that worked. Heaven help us, indeed.
