I loved this show. The acting was the best you'll ever get. I found myself often relating to the stories of several episodes. I loved the mother played by the late Sada Thompson. She was stern, but made a lot of sense and was a strong foundation for the family. Kristy McNichol was brilliant in this show. What a smart girl. Whatever happened to her? The series was made up of many stories depicting problems and joys of life. The parents had excellent morals and coached, loved, guided, and cherished their children. The show dealt with some very risqué topics during the 1970s - breast cancer, divorce, single parenting, homosexuality, and bullying to name a few. There were other stories of acceptance, sorrow, happiness, accomplishments, love, and much more. The stories may be old but they are relevant today. While viewing this you'll realize that the issues of the world have not really changed that much. This series is timeless. The writing and acting could not be better. Just start watching it and you'll be hooked!
My only disappointment is with Sony who has only released seasons 1 and 2. Years later, seasons 3 through 5 are still unavailable. It's really a shame that they don't release the rest of this golden treasure. I'll keep checking with my fingers crossed.
