A powerful and highly informative feature-length documentary by the Testing the Limits collective (Robyn Huff, Sandra Elgear, and David Meieran) about AIDS activism and, more specifically, the self-empowerment of people with AIDS and AIDS-related diseases. Two of the more eye-opening subjects broached here are discrimination against women with AIDS and the drug profiteering that is promoted and protected by the Bush administration. Many people tend to be scared away from documentaries of this sort because of the unpleasantness of the subject matter, but the passion and determination of the activists seen here (including quite a few, such as Vito Russo, who are no longer alive) make this inspiring rather than hopeless–if only because we see that these activists have been far from ineffectual (1990).
