How can a four year old remember the pilot episode of a show? I don't know, but I do. Groundbreaking at the time, it actually featured a divorced mother with her two kids. Very topical, and sedate by today's standards, this show was a huge hit. Of all the people on this show who would have thought Valerie Bertenelli would have the biggest career? And who knew McKenzie Phillips was on heroin? Totally watched during the seventies but everyone pretty much was over it by the early eighties. Still one of the coolest shows of the seventies.
