Season 4, Episode 13 left us feeling optimistic, the way people who visited Disneyland's look into the future must have felt -- until the second half of the 1960s rocketed us into a future that wasn't as bright as we thought it would be. It was a most satisfying ending to thise great season because it makes us eager to see what happens next but filled with dread, too.
Don Draper makes one of his signature impulsive moves, trying to improve himself. Peggy Olson gets high on work. Betty Francis acts like a child. And Joan Harris takes care of herself.
