Part Empty Bottle, part Garfield Goose and Friends, the cable-access dance program Chic-a-Go-Go has become a hipster touchstone and a local institution. Directed by Jake Austen, this big-screen spin-off is so cheerfully amateurish it's beyond criticism—and besides, I know half the people in it. The plot is lifted from the old American-International flick Shake, Rattle & Rock (1956), with two horrible old squares trying to get Mia Park and her puppet cohost Ratso banned from the airwaves. There's too much feeble comedy and not enough music, but how can I knock a movie with Milt Trenier, late of the Treniers, lip-synching their 1956 recording of “Good Rockin' Tonight”? With Kelly Hogan, Bobby Conn, Sharkula, Don Stroup, La Donna Tittle, Mike Miller, Sergio Mims, Eric Nix, Lawrence Peters, and Derek Erdman. 62 min.
