Ouch. Miscast as a hairdresser, Arquette gets whipped, beaten and mutilated because Christ thinks the church is getting carried away with itself. Byrne's turn as a scientist-turned-priest offers a bit of humanity, but Pryce as a Vatican City villain is absolutely ridiculous, sending Byrne to investigate miracles and then saying he's too involved in his cases.
Director Wainwright tries to use horror tactics that worked well in Sixth Sense and The Blair Witch Project, but the gallons of blood spilled here only make the audience queasy, not frightened. And having Arquette speak in acid tongues and endure an out-of-body experience doesn't scare anyone; it just makes us wistful for the days of The Exorcist--minus the pea soup, of course.
