I remember back in 1979 when The Facts Of Life debuted it was a nice show, but lucky it got a second chance when it got retooled and revamped and streamlined. When it first debuted there were about six blond teen girls plus two other, a young black girl played by Kim Fields and a stout young girl who was Mindy Cohn. The rest were a group you could barely tell apart.
The following year this show about a girl's boarding school underwent a huge makeover. All the anonymous blond teens went, save one played by Lisa Whelchel. She stood out somewhat because of her character as a rich teen débutante who avoided serious subjects like the plague and thought her money fixed all. Over the years Whelchel's character grew somewhat.
But the show needed a contrasting bite and it got it when Nancy McKeon joined the cast. When she rode in on that motorcycle, bad girl in the making what it made was the show. Now you had potential for real conflict on the episodes.
Whelchel, Fields, Cohn, and McKeon pulled a real nasty prank on that first episode and were put in some kind of permanent probation living with school counselor Charlotte Rae. She became a strict but loving den mother to the four of them as they went through puberty learning The Facts Of Life.
With a few tight scrapes they learned them well. If the show wasn't completely realistic it wasn't exactly the Fifties either. The kids had some real issues, but it was all done PG.
It was also good entertainment.
