Director Brett Morgen hasn't made a fuzzy nostalgia trip for people who went to the Democratic convention in 1968—he's made a rousing primer for people who might go to Denver (or perhaps Minneapolis) this summer. The documentary part covers logistics, media management, and fuck-the-man speeches by Abbie Hoffman, Jerry Rubin, Rennie Davis, et al. The animated part, a re-creation of the infamous trial, resembles a video game. And the soundtrack (Rage Against the Machine, Eminem, Black Sabbath) completes the message: Rockers, rappers, and metal heads can protest, too. (See movie times for details.)
