My prime time years of television watching were in the '60s and '70s and given most of that time I was a stupid kid, a lot of those shows were right over my head. Sure, as a kid I might have got a lot of entertainment from rather simplistic TV shows--but when I go back to watch the regular prime time TV shows, I get a lot more out of them because I'm not so stupid anymore.
I recently rediscoverd ROOM 222 (unfortunately youtube took it down before I could get through the first season). I was blown away by this show (the creative talent behind it would go on to create THE MARY TYLER MOORE SHOW). It was only a year after MLK was assassinated that ROOM 222 made its debut. Here is a show with an African-American actor in the lead, as a strong, intelligent and inspiring figure. The cast is evenly divided between male and female. All races and religions are represented. It's funny but informative and never talks down to its audience. We don't see this kind of integration on TV anymore. It's a shame because ROOM 222 shows a path forward for America that could have brought greater understanding and harmony.
As a kid I just thought Karen Valentine was really cute.
Now not every show is likely to be better on second viewing. However, there were only three networks with three hours a night of prime time TV in the U.S in the old days. So for that low output of shows, I think American TV did quite well in producing quality programming. Compare that to today with thousands of channels plus the internet--it seems like there's a much higher percentage of schlock coming out of the sausage factories. For every show like BREAKING BAD there are hundreds like SELFIE--just because all those channels need content to fill their hours.
*Edit: I just checked youtube and ROOM 222 (season one) seems to be up again. But keep it under your hat--who knows how long these eps will stay up. I'm going to watch as many as I can before that happens.
