Don Draper is not real. I don't care about the real McCann Erickson guy who thought up the iconic Coke commercial, "I'd Like To Teach The World To Sing". And I'm not interested in speculating about how Don would have fought through the corporate culture at McCann to sell his concept. The ending of the Don Draper part of the series finale was just so perfectly cynical and so in character for Don, that it deserves to stand on its own. That's how that character in this story would have pushed through his darkness and gloom to re-invent himself once more at an ashram, taking out of the EST-like group therapy "seminars" those elements he needed in order to experience the breakthrough that would propel him forward.
Last night's series finale of "Mad Men" was very satisfying for me. As someone who has watched every episode more than once, I had imagined several different ways that Don/Dick's story might have ended. But the image of Don "finding" himself at the Northern California retreat - putting himself through the hippy-dippy seminars and using his experience as a vehicle for his own self-discovery - was wonderful. That he came out of that with the concept for the iconic McCann Erickson Coca Cola ad was so perfectly cynical and so perfectly reflective of what the show has always been about that it almost brought me to tears. Well, not really. But you know what I mean.
And I love the way Matthew Weiner inserted a sneaky preview in the penultimate episode, with Don attempting to fix the motel Coke machine, of how Coke would be at the core of Don's epiphany on the mountaintop.
