No need for a story line that turns out to be so simple to be so confusingly presented in the first half. Aren't writers taught how to convey relationships in the form of dialog to help the audience follow the action any more? This problem almost sinks the movie, until after a while when it does become coherent. Last half hour or so is quite terrifying as you realize the extent of the family's commitment to their insane (there is no other word) religious beliefs. The performances, especially by Olivia Coleman and the actor who plays the preacher, are first rate. A low budget version of the similar idea in the recent MIDSOMMAR, though not nearly as effective.
