As someone who grew up in the 1970s, I found the concept of Swingtown to be interesting. That said, I found the show to be extremely enjoyable and if someone, most likely not CBS, chooses to bring this back for another season, I would watch it. Once I got past the first episode or two, watching the development of the characters was fascinating and how they reflected the changing norms of the time, especially about sex and women's rights. I did catch a couple of errors in watching the series, as a few people have noted on here and I agree one hundred percent that if the show does come back, someone should get their facts straight. Overall, it was the best new show on television this summer and worth watching.
