Launching out of a clever premise (a woman posessed by an evil entity is forced to perform an exorcism on herself), this movie takes a fast and unpredictable trip to its gripping finale, with some real emotional beats along the way. Sadie Katz's performance is pure and raw and authentic, and it's impressive to know that she conceived, wrote and produced his project. It's undeniably a small film (budge wise anyway) but's very effective. It has a lot on its mind besides just being scary: It deals wih questions of faith, fidelity and friendship. Nice photography and effects, and all of the performances are Grade A.
