And then, there's Maude.

 The Norman Lear sitcom, Maude, ran when I was just a little kid. I knew of it, but it made no sense to me, and it felt like a chore to watch it, if I ever did. I just found it boring. Maude's daughter, Carol, was particularly annoying to young me. Why did they have dull neighbors, too? Mom, what are they talking about?

I recently watched a few episodes of the show, and, my god, it was great television. Every character was interesting. The stories are solid.

I may have misjudged the 70s.
