Throughout, Glauber Rocha calls on us to imagine what we’d want a revolution to look like.

For all its heroic energy, hortatory anger, and impulsive youth, it's very much a philosophical work of its time, a majestic fantasy of no way out.

Simple, black-and-white, more arresting as a shocking polemic than as memorable drama.

A strange film, both of its time and blisteringly immediate.
