WE CAN STOP: Hank and Marie watch the VMAs.
Let's be clear: there's nothing "shocking" about a female performer (whether singer or actress) choosing to go all sexual to prove she's all grown up, whether it's Olivia Newton-John's long trek from Sandra Dee to getting "Physical," Anne Hathaway in Havoc and Katie Holmes in The Gift, or the multi-car train wreck which remains Britney Spears' career despite Isaac's love for "Toxic". This is a path which pop culture lays out fairly plainly for women in entertainment, and those who follow it tend to get the bargained-for results.
[Speaking of which: it wasn't a "train wreck" either -- Cyrus did exactly what the choreography called for, and elicited the desired media cataclysm in which I'm now participating. If you want to see a languid train wreck, watch Spears at the 2007 VMAs.]
Let's save terms like "controversial" and "shocking" for when they're deserved: Sinead O'Connor's or Elvis Costello's SNL performances, Dylan at Newport, RuPaul's vicious undermining of Milton Berle at the 1993 VMAs (because of an off-stage slight), etc., performances which actually challenged audiences. Sunday night was a nontroversy.
