Revolution, an interesting quasi-documentary on the hippie experience in San Francisco, presents a day in the life of Today Malone, an attractive blond hippie (who might just be an attractive young actress playing a hippie). As with many of such films from the era, we're treated to lengthy pro- and anti-hippie banter, hallucination scenes, free-love themed nudity and excellent music (in this case, Country Joe and the Fish, The Steve Miller Band and Quicksilver Messenger Service, all at the creative peak of their careers). While at times absurd, this film nevertheless provides a fascinating document of the environment of hippie San Francisco, even if seen through exploitative eyes. As with the garbage on eBay, one needs simply to filter out the garbage to find the invaluable treasure.
