The Star Wars creator has been looking to build a home for his collection of Narrative Art Museum for several years. And the saga has nearly as many sequels as Star Wars itself. Now Lucas has set his sights back on the West Coast and has pit LA and San Francisco against each other. And he has offered each a design by Ma Yansong. But along the way art critics have been dismissive about the "narrative art" collection itself. We will hear from a San Francisco Chronicle art critic who argues it could just be the "core of a great museum."
