I recently went back and watched all the episodes. The general vibe I get from the show is that it challenges Hank and Peggy fairly often with a typical (for the time) conservative issue. They start with a stereotypical response to the situation, but by the end of the episode, they have learned to be more accepting of the world around them, without sacrificing their own way of life. Maybe I’m overthinking it, but I enjoyed it more than I thought I would.
Growth.
