The convulsively entertaining RocknRolla is Guy Ritchies strongest outing to date, even if it is just another of his trademark boys-with-guns gangster flicks. Narrative cohesion has never been Ritchies strong suit, and it takes about a half-hour to realize that the films shaggy-dog story doesnt make a lick of sense. What truly matters are the rogues gallery of colorful criminal lowlifes, Ritchies undiminished flair for writing gleefully profane, uber-stylized dialogue and some strikingly original action set pieces. David Higgs eye-popping high-def cinematography is the best advertisement for Blu-ray since Speed Racer, and the polyglot soundtrack (heavy on vintage Clash) kicks ass like nobodys business. Ritchie may never become a major artist hes still too beholden to the Tarantino playbook of postmodern hooliganism but he has the instincts of a first-rate entertainer. And in a dispiriting fall movie season where fun has been in conspicuously short supply, RocknRolla delivers the goods. HHH 1/2
