Commentary - Sundance Film Festival The Sundance Film Festival is going on through Saturday in Park City, Ut. Sundance has been widely credited with bringing independent films to mainstream audiences. Commentator Jake Tapper is in Park City this week, covering the festival for the Sundance Channel's nightly show. He says that one thing that distinguishes an independent film is that it is highly personal -- about the filmmaker's own revelation or catharsis. But just because an idea or subject is important to a filmmaker does not mean that the rest of the world will be moved by it.
