"The personal is political" in Mary Dore's documentary about the women's-liberation movement of the late 1960s and early '70s. It's necessary and illuminating history for anybody who didn't live through it — and it's worth noting how much changed simply because ordinary people rose up and demanded it. Dore traces the movement back to the activism of the civil-rights protests, then details the various offshoots women formed with more specific focuses (black women, politics, street activists, health care, lesbians). First-wave feminists recount their experiences, with plenty of humor, and there's ample archival footage depicting everything from small meetings to blockbuster street marches. The title is an apt bit of wordplay, reclaiming empowerment from a phrase often used by men to patronize women's anger. And mulling over what has yet to be achieved, this film might inspire a new wave of productive anger.
