Throughout, the film refers to comic-book imagery--with Dunn's security guard slicker coming to look like a cape, and Price's gallery taking on elements of a Batcave-like lair--while the lectures on artwork and symbolism feed back into the plot. The last act offers a terrific suspense-thriller scene, which (like the similar family-saving at the end of The Sixth Sense) is a self-contained sub-plot that slingshots a twist ending that may have been obvious all along. Some viewers might find the stately solemnity with which Shyamalan approaches a subject usually treated with colourful silliness offputting, but Unbreakable wins points for not playing safe and proves that both Willis and Jackson, too often cast in lazy blockbusters, have the acting chops to enter the heart of darkness. --Kim Newman
