There's a part of every great film and television show that is wish fulfillment for the viewer.... But we watch Don Draper and we worry about him. He re-committed to Betty and their Westchester ideal at the end of season two, only to court (and eventually find) disaster once again in season three. Throughout, he gropes, fecklessly, to make himself whole, flailing between poles of eros and thanatos. He's spent dozens of episodes building walls of traditional happiness, only for the deviant pleasure of plunging into the dark and knocking them down once more.
