It’s also a love story (Jennifer Connelly is Betty Ross, touchingly torn between desire and horror) and a meditation on fathers and sons (Nick Nolte, disheveled and deranged, plays Bruce’s mad-scientist dad). Lee takes his time getting to the action, but he doesn’t skimp when he gets there. Most spectacular is the desert showdown between the Hulk and a phalanx of Army tanks, which he flings across the dunes like so many Frisbees. “The Hulk” sometimes meanders, it has too many endings for its own good and the computer-generated angry green giant sometimes moves with cartoonish clunkiness. But where so many comic-book movies feel as disposable as Kleenex, the passionate, uncynical “Hulk” stamps itself into your memory. Lee’s movies are built to last.
