DOC FEST AT MMI! The documentary is probably the most under-rated film genre of the past 50 years. Tomorrow, Astoria's Museum of the Moving Image launches a festival of documentaries handpicked by film critics including Michael Atkinson, J. Hoberman, Dennis Lim, Leah Rozen, and Andrew Sarris. Take a look at the roster and see if you can pick at least one--they all look worthwhile. One enjoyable and relatively obscure pick is East Side Story (Sunday, February 4, 4:30 pm), about Iron Curtain musicals.
