Metacritic reviews

Darren Lynn Bousman's St. Agatha goes so full-bore into the scary nun trope it's practically nunsploitation, and the mood he establishes — the look and feel of the claustrophobic "convent in the film — launches St. Agatha into a weirdo plane of phantasmagorical psychological and physical torment.

St. Agatha is a fine thriller that is much better than you will expect it to be. Bousman guides a coherent and nimble narrative to shocking and satisfying builds.

St. Agatha is less overtly gory and supernatural-oriented than most efforts of its ilk, such as the recent "The Nun," but it provides plenty of chilling, if slow-moving atmospherics and strong performances.

Kern and Hennessy are always incredibly entertaining, going toe-to-toe, as Mary defies the convent’s rules and a smiling Mother Superior makes her pay.
