The highly anticipated pairing of martial arts masters Jackie Chan and Jet Li comes to a head in this entertaining (if shallow) fantasy-adventure. Formulaic but engaging tale centers around a callow American youngster and avid kung fu lover who's transported to ancient China where under the tutelage of a boozing immortal (Chan) he goes on a perilous mission to return a mystical staff to its rightful owner: the one and only Monkey King (Li). Slim story ingredients are mostly just a ploy to put Li and Chan in the same film, fortunately they're both in great form (Li with his quickness and agility, Chan with his irrepressible charm and energy) delivering dazzling, one of a kind fight scenes, aided by a script that doesn't require lots of thinking and has a wonderfully silly sense of humor. Swift, flashy, and full of action it never reaches the level of awe-inspiring, but still delivers the goods thanks to its two formidable stars. ***
