As someone who grew up in that era, protested Vietnam (and was gassed) in Boston and watched friends get drafted, this encapsulation of the energy and the caustic change to American culture in this film captured so much of what was going on. It may be difficult for people who were not there to generalize to the swath of American youth (and not-so-youth) who were at the core of the causes and the actions but it was an era of social bifurcation and norms upheaval the likes of which America had not seen since the Civil War. Neighbor against neighbor, police against alternative lives, justice mishandled, etc. It's a film so it smooths over some of the rough edges in telling the story but the inclusion of some of the footage of the Chicago riots and the sense for how policing was done in particular is worth the price of admission.
