A fantastic and fascinating documentary by Errol Morris, where former defense secretary Robert McNamara delivers an account of his political life in the form of a confession, at times weeping. A perfect insight into the real world where there is no such thing as the good guys and the bad guys; just impossible decisions, compromise and eventual moral bankruptcy. The film looks into major political event of the 20th century; such as the Kennedy Administration handling of the Cuban Missile Crisis, plus how Vietnam policy dramatically changed once Kennedy was no longer in office.
