"Nobody thinks you're happy, they think you're foolish." We have seen Don this happy before, when he was describing Betty to Anna. And then look what he did to Betty. After an attempt at a redemptive arc all season, Draper is back where he was in 1960 - the whole wife and kids life that didn't make him happy. Weiner said the season's theme would be "Who is Don Draper?", and it is anticlimactic to have us already know who he is. It is also anticlimactic to have the past three episodes starting an arc about how the agency is in deep trouble and then not resolve it somehow. It will be lame if the next season starts in 1966 and the firm is suddenly successful with some big clients when we never saw how it happened.
