BELOW (2003)

Submarine movies from ''Das Boot'' through ''U-571'' always have the same elements -- the claustrophobic denseness, the salty crew, the thrill of a hull-popping descent; they've almost become fetishistic. ''Below'' doesn't disappoint -- director David Twohy (''Pitch Black'') wields every creak, clank, and moan like a master of atmosphere (do yourself a favor and watch the DVD on a decent home theater for the full effect). If only all of that sound and fury signified something: The grafted-on ghost story leaves a nimble cast submerged beneath lots of spook, and the little substance present is floating just out of arm's reach.
