It seems like over the last decade there's been a veritable cavalcade of movies about exorcisms, hauntings and paranormal activity, so it's hard to build up any enthusiasm for yet another one. But Sir Anthony Hopkins is a game-changer. Having such a fine actor in such a formulaic genre film, even one purportedly based on a true story (but aren't they all?) seems like a waste, but at the same time it's always fun to see the man really cut loose, as he did in Dracula and The Wolfman and a dozen other horror and thriller movies. Add this one to his list of masterful performances, because he single-handedly makes the movie a horror staple.
