Richard Brody’s New Yorker review is titled: “Quentin Tarantino’s Obscenely Regressive Vision of the Sixties in “Once Upon a Time . . . in Hollywood”“.
I didn’t love the film, and with each work of his I see, the more I like the others (and him?) less. My main takeaway was to be reminded of an enormous and unprecedented historical shift. In the 1960s, in part because of the birth control pill, the sexual opportunities of high status heterosexual men, or even medium status men, increased enormously, in terms of both quantity and quality. And indeed the men in this movie take advantage of that, to various extremes (wife murder, the Manson cult) and it is not entirely clear how much Tarantino disapproves.
Whatever your normative view of this change, keep it in mind the next time you encounter the “Puritan excesses” of today’s PC movement. Very rapid historical shifts in norms do in fact bring various forms of reaction and sometimes overreaction, and pushing back against the overreaction is not always the wisest thing to do.
If you want to see southern California on the big screen, you might enjoy Echo in the Canyon more, while its bookend cinematic partner David Crosby: Remember My Name will fill in the Joni Mitchell blank and also show you how deeply unpopular and unlikeable people talk and think about themselves.
