Director Rob Cohen treats this like Roman tragedy for MTV junkies, pushing every scene to adrenaline-pumping extremes; when his camera isn't caressing a spectrum of nitrous oxide-enhanced dream machines, it's ogling countless slim 'n' sexy race babes. The undercover-cop scenario cheaply borrows the split-loyalty theme perfected in Donnie Brasco; a rival Asian gang adds mystery and menace; and digital trickery is cleverly employed to explore the fuel-injected innards of the day-glo racecars. It's about as substantial as a perfume ad, but just as alluring, and for heavy-metal maniacs of any age, Diesel's superblown '69 Charger proves that Detroit muscle never goes out of style. --Jeff Shannon
