With the Sundance Film Festival fast approaching, we're launching our Countdown to Sundance, where the Movieline staff (and some special guests) will break down all the notable films and events Park City's got to offer this year. First up for our video dissection: The Runaways, Floria Sigismondi's high-profile band biopic starring Kristen Stewart, Dakota Fanning, and a conspicuous drop of blood. Ever at your service, I offer three things the film has going for it -- and three against.
