“The Nun” (*1/2 out of four) was an unholy mess about a priest (Demian Bichir) with a troubled past and a novice (Taissa Farmiga) on the threshold of her final vows who are sent by the Vatican in 1952 to investigate the mysterious death of a nun in Romania which leads them to (yawn) a demonic nun and various paranormal activity. Allegedly a prequel to “The Conjuring” but you’d be hard-pressed to tell because it’s yet another umpteen religious horror movie about Satanism and exorcism within the church which makes you wish horror filmmakers would finally conjure up some new ideas. Film finally gets going in the final third but it’s too far gone to matter.
