i believe this series hold up pretty well. some of the clothes and hairstyles are just awful, but the characters are great. Stuart McMillan (Rock Hudson) and Sally McMillan ( Susan Saint James) were a recently married couple. Mac is quite a bit older than Sally. he used to be an attorney and now he is the police commissioner of San Francisco.
Mildred (Nancy Walker) used to work for Sally's mother, but when Sally married, Mildred went with her. Sgt. Enright ( John Schuck) is mac's assistant. both these characters often serve as comic relief for the show.
Mildred was also a wonderful character; loyal, sarcastic and funny. even Enright had his moments. they sure drank a lot on the show and twice they found a body in their house (and they didn't move!!!) also the police commissioner doesn't actually solve crimes, and certainly not with his wife's help.
in the last year, they killed off Sally and Mildred left, so the series didn't end well. they should of just stopped at season 5 with Sally alive. At the end of season 1 Sally was pregnant but she didn't actually have a baby until season 5 and they never explained it. Also, the baby, it was a boy, was never given a name. So there were some continuity errors on the show, but it is still a pretty enjoyable one.
