Dennis Quaid grits his teeth and knits his brow as Frank LaCrosse, an FBI agent so monotonously dour he makes The X-Files? Fox Mulder seem like Richard Simmons. After a serial killer kidnaps his son, LaCrosse goes AWOL from the bureau and trails a retired railroad man (Danny Glover, killing time between Lethal Weapons) and a mysterious drifter (My So-Called Life cipher Jared Leto), one of whom may be the culprit. In his directorial debut, screenwriter Jeb Stuart (Die Hard) ladles on the clichés?a barroom brawl, a train-top chase?and lets his narrative get bogged down in a boring subplot about a local sheriff?s election. The thoroughly routine SwitchBack may ultimately be remembered as the year?s most forgettable movie.
