This meaningless death spree from George Tillman Jr. is really complicated only by terrible plotting. An ex-con -- known here as "Driver" (Dwayne "The Rock" Johnson) -- sets out to avenge his brother's death by tracking down the hombres who killed him, and killing them. Meanwhile, "Killer" (Oliver Jackson-Cohen), a hitman, is stalking Driver. In another corner is "Cop" (Billy Bob Thornton), a junkie detective, who lands the case of Driver's first kill. Bang, bang, bang. Everybody's shooting at everybody else, and despite their bad-ass reps, half the time they're missing the targets. It's utter nonsense, stretched out with lots of loving shots of Driver's Chevy SS. The story feels like discarded scraps from The Shield, and the ending is obvious and unsatisfying. The biggest mystery, really, is why The Rock is back to this violent drive-in-movie junk after successfully carving out a new career as the star of kid-vid and comedies. Johnson can be a funny and engaging actor, but all he does here is glower. Feel free to glare right back.
