This episode was always going to be controversial. The producers have decided to make the 19th episode of every season a format-busting departure, a pattern that began in the second season with the woeful “Brown Betty”. Each departure has been a love it/hate it moment for the audience, and with the added anxiety over the future of the series, a lot of fans were concerned that this would end up being a needless waste of much-needed resolution time.
Pete Campbell has everything anyone could ever ask for. A successful job, a doting wife, a child, a house in the suburbs. So why is he looking for more instead of accepting how good he really has it? It probably has something to do with his stunted growth and adaptation to his adult personality. He is, in essence, a spoiled rotten child in an adult body.
