Vin Diesel stars as an immortal witch hunter in New York City, tracking down practitioners of black magic and showing them who’s boss. His controlled, smirky performance sets the tone for this effects-laden action fantasy, which verges on self-parody but never quite takes the plunge. The special effects are pretty neat, and the filmmakers utilize them smartly, delivering imaginative set pieces that are more visually compelling than the usual series of digital explosions. Among the highlights are some scene-shifting hallucination sequences and a monster made from rotted trees and pieces of human skeletons. Breck Eisner directed; with Michael Caine and Elijah Wood, providing some gravitas as priests who assist Diesel.
