Worth the time to revisit especially in today's money-making military-industrial complex. Colonialism & imperialism are often ugly: be prepared for disgust as this work adeptly weaves historical footage (lots of white-male talking heads) as a means to untangle the complicated mess of the Vietnam War. The approach is decidedly anti-war; the effect is certainly thought-provoking; and the visceral reactions of the work's first audiences probably speaks to the filmmaker hitting a nerve--perhaps the same nerve most humans have when confronted with such an ugly truth about themselves that hostility & denial ensue.
