I finally got around to watching my tape. I didn't love it, but it's interesting enough to keep me watching. Certainly, the production design and costumes are dead-on for 1960, even if some aspects of the portrayal of the office and sexual politics of the time are stereotyped and exaggerated. I don't know that the series is exactly *necessary* (Billy Wilder's "The Apartment" really says it all as far as this subject goes!), but it's nice to see an attempt at something different, and the cast is certainly attractive.
Speaking of which, fans of the late lamented "Firefly" should note that Joan (who I also thought was a standout character) is played by Christina Hendricks - Mal's "wife" Saffron. (The con artist aka Bridget, aka Yolanda!)
