The Sundance Festival opens today in Park City, Utah, with 120 feature films and 73 shorts on the schedule. And as usual, the “true indie” filmmakers will complain that the fest has forgotten its roots and become a pawn of the major studios. These detractors certainly have a point, but Manohla Dargis says that “despite the hype and the frigid climes Sundance remains invaluable – wildly annoying, but invaluable. The American independent film movement may be a fiction, but it is the fiction we now live by.”
