In driver's ed, we learned the S.M.O.G. method when changing lanes: Signal, Mirror, Over the Shoulder, Go. Ben Affleck and Samuel L. Jackson, both speeding through life, have no such system, and they bring road rage to new levels in this drama of ever-changing protagonists, revenge and despair. After a fender bender on the FDR in Manhattan, courteousness gives way to violence, and the two socially and economically different men begin to hurt each other in life-altering ways that certainly aren't covered by AAA.
Director Roger Michell ratchets up the drama, with Affleck (doing that smug rich-guy thing) and Jackson (doing that intense everyman thing) raising the stakes each time. The morality aspect of the film is a bit simple-minded, but that's no reason to stay away. Like an accident on the side of the freeway, this adept and stylish pileup is hard to not look at.
