Film scores and their composers (and their relationships with directors) could make for a fascinating multi-part series. It’s therefore dispiriting to read that Dan Lieberstein‘s Lights! Action! Music!, a doc that airs tonight on New York’s WLIW , is, in the opinion of N.Y. Times critic Stephen Holden, “a fluffy, disorganized, woefully incomplete compendium of interviews and film clips about movie music…a sampler for a larger and deeper exploration….even on its own terms, a frivolous diversion.”
