Lightweight storywise--but no more so than a modern James Bond movie--"Shaft" is nonetheless stylish and entertaining, even with some scenes of terrible violence. Samuel L. Jackson makes a worthy successor to the family legacy of being supercool, playing the same sort of urban 007 Richard Roundtree brought to life in the Shaft films of the 1970s. This time, the nephew of the original clashes with a brutal racist and a showoff drug kingpin who have joined forces to stalk the only witness to a savage murder. Director John Singleton keeps the energy constant, helped in part by Isaac Hayes' terrific theme and David Arnold's incidental music, though the occasional quick zoom gets annoying after a while. Taken as entertainment with a little social commentary, "Shaft" offers little to dislike, except, perhaps, the brief appearance by Roundtree, who also seems more mellow and unhip this time around.
