Here’s one promo screening I don’t mind flacking: Michael Moore’s new documentary, Capitalism: A Love Story, screens at City North 14, 2600 N. Western, on Thursday, October 1, 8 PM, with proceeds to benefit Warehouse Workers for Justice. Introducing the film will be leaders of the December 2008 worker sit-in at Republic Windows and Doors, an incident that provides one bright ray of light in a decidedly dark movie.
