Part 1 is tremendous, but it's downhill from there
Part 2 remains neutral and informative.
Part 3 is filler laden, repetitious and far too opinionated and biased to be taken seriously. The low point for me was when the neo-cons were accused of forcibly manhandling Bill Clinton's ding-a-ling leg into the mouth of a reluctant Monica Lewinsky. Grrr..those dastardly neo-cons, they'd do anything to get power.
