I feel like the same sort of vitriol that’s being directed at Miley is the same sort that was directed towards Elvis near the beginning of his career. “But Chaaaaan,” I hear you whine, “Miley is no Elvis. She’ll never invent the new rock and rooooooll.”
If by “invent rock and roll”, you mean “appropriate black R&B and repackage it for white teens,” then I’d say she certainly has done that to an extent. She’ll also never be Elvis for the same reason that Conan will never be Carson: The media landscape that allowed those people to influence culture to that extent no longer exists. That’s beside the point.
The point is, the criticism leveled at Miley is run-of-the-mill, Footloose parents-variety, old fogey moralizing. Miley’s “outrageousness” - be it her lewdness or narcissism or even just odd staging choices - is just hip-shaking and you’re a sad, snarky biddy mis-remembering the past.
