Do we need a better history of the hippy era?

Sergio, the dramatic, inspirational doco on the life and death of Sergio de Mellor, is more about the latter than the former. However, I noted that his idealism sprang up after a radical period at the Sorbonne in 1968. In other words, though it wasn’t put that way, he was a hippy, or at least imbued with that unique blend of hope and idealism the late 60s engendered. Recently, I’ve seen a number of revisionist histories of the hippy era, claiming it wasn’t really about peace, love and understanding, but was a tawdry period of selfish hedonism. A notable exception to this trend is Mark Kurlansky’s life-affirming 1968: The Year That Rocked the World. I wish one of the brilliant, less ideological historians of this world would document that era and its ongoing influence through the next four decades.
