Based on a real character from the murkier side of quite recent Vatican operations, Russell Crowe dons his cassock and travels to a remote abbey in Spain where his meets with "Fr. Esquibel" (Daniel Zovatto). Why? Well it seems that a young boy is being possessed by a singularly nasty demon. Now Fr. Amorth is not unused to these scenarios and is also aware that the vast majority of these situations have nothing to do with satanic practices and more to do with mental health issues. Quickly, though, he realises that this is a serious and potentially deadly demonisation and both he and his colleague must discover what went on at this place and just who their violent foe is, before they can have any hope of casting it back into the shadows. That's the plot, and to be fair Crowe actually plays his character with a bit of charisma, but the rest of this is the same old loudly scored, visual effects feast with plenty of routine dramatic scenes: screaming, eye-popping, ceiling climbing, bodies and holy water thrown about the place and this one even has a bit of the Spanish Inquisition thrown in for added authenticity. It's not that is terrible - it isn't; it is just all so very derivative. Just because the exorcist was real doesn't actually make this film any different from an whole spate of other similar films that have the same beginning, middle, and end... It will do fine on the television around Halloween, but the cinema adds little to the presentation. It's nice to see that Franco Nero is still making films, but otherwise this is adequate, but nothing more.
