Fantastic action, albeit cartoonish fight scenes. Jason Stetham's acting and casting is superb for this role. The ultimate bad*ss, witty, the edgy personality, extreme athleticism that rival Jackie Chan. Great plot concept, Stetham backs out of a contract hit for underworld bosses, who retaliate in kind. He comes out of a trance, and discovers he's been injected with a lethal cocktail that keeps his body's from producing adrenaline. His doctor friend informs him his short life will only be prolonged by insane activity that creates adrenaline pumping through his veins. Insane physical activities ensue, buying him time to find his employers who poisoned him and to seek revenge before he keels over. Great handheld digital cam action sequences in inner city Chinatown. Amy Smart plays the airy, sexy neurotic girlfriend role perfect.
