Russell Crowe takes on the role of a character inspired by events from relatively recent Vatican history, portraying him in religious garb as he journeys to a secluded Spanish abbey where he encounters "Fr. Esquibel," played by Daniel Zovatto. The reason for his visit turns out to be a young boy seemingly possessed by an especially malevolent demon. Fr. Amorth isn’t unfamiliar with these kinds of cases and acknowledges that most are often attributable to mental health concerns rather than actual demonic activity. However, he soon recognizes this situation as genuinely dangerous and potentially lethal, requiring him and his assistant to investigate the abbey's history and identify their adversary before they can attempt to banish the demon. That’s essentially what happens in the story; Crowe brings a certain charm to his performance, but beyond that, it’s another loud, effects-driven movie filled with predictable dramatic moments—screaming, eyes bulging, people climbing on ceilings, water being splashed around, and even a nod to the Spanish Inquisition for some extra historical flavor. It's not awful; it simply feels like countless other movies of its kind, following a familiar pattern from start to finish. It’ll likely be acceptable viewing on television during Halloween season, but seeing it in theaters doesn’t really enhance the experience. It's good to see Franco Nero is still working, but overall this film is serviceable, though unremarkable.
