Plot: In Baton Rouge, Louisiana, the evangelical Reverend Cotton Marcus was raised by his father to be a preacher. He agrees that the filmmaker Iris Reisen and the cameraman Daniel Moskowitz make a documentary about his life and he tells them that exorcisms are frauds but the results are good for the believers because they believe it is true. When Cotton is summoned by the farmer Louis Sweetzer to perform an exorcism on his daughter Nell, Cotton sees the chance to prove to the documentary crew what he has just told them - that the exorcisms are fake but because others believe in them, they have a healing effect. They head to Ivanwood and they have a hostile reception from Louis's son Caleb. Cotton performs the exorcism on Nell, exposing his tricks to the camera, but soon they learn that the dysfunctional Sweetzer family has serious problems.
The heroes: Reverend who is angry with God and who is more of a magician performing tricks than the actual exorcist.
The antagonists: Maybe a demon, maybe a human being. Equally dangerous, though.
What makes it so great? The documentary-inspired style and shaky camera - you never know what it may catch on frame during its frantic movements. Also Ashley Bell's performance as Nell - who curiously did all the weird body movements herself without use of CGI - is quite remarkable.
Best scene: The exorcism inter vined with Reverend showing us how he deceives his audience.
