Something has gone horribly wrong in the specialty film business. Movies are dying left and right, with even the modest successes doing half of the business they used to do. What's worse, this isn't just a two-month slump. This is a real art-house depression. You have to go back to the fall of 2006, when "The Queen" and "Babel" were released, to find a specialty-division drama that made as much as money as a forgettable piece of fluff like the Jessica Alba comedy "Good Luck Chuck."
