Skip this See Jonestown: The Life and Death of Peoples Temple
I honestly don't understand Ti West as a horror director. He has absolutely no sense of how to build tension. The documentary draws us in and we, even knowing the outcome feel the dread. In The Sacrament, even though it's fiction and could have done its own thing, we're just carried along, expecting a huge climax and there is none. Not a single scene contains any tension and the ones that attempt it are destroyed by the silly found footage angle (which is horribly shot).
I still haven't seen The Innkeepers, but this is another 1 star attempt by Mr. West.
