There were certainly some classics like Twilight Zone and Hitchcock and some great westerns, a genre which I really love.
However, a lot of shows have not aged well. They were so formulaic and predictable (and cheesy). Many were not realistic: husband and wives didn’t share a bed; Westerns painted native Americans and Mexicans in shallow and racist ways; blacks were underrepresented and/or stereotyped, etc. Life was painted as black and white with no shades of grey. The good guys always won.
Children’s shows are much more educational than they were in the 50s and 60s and have a great deal of moral content as well.
Certainly there are too many “reality” shows which aren’t really realistic. Quality content is sparse but I also think there is a great deal of social and moral content in shows like Young Sheldon, Mom, The Neighborhood. A lot of quality shows are being presented on streaming services. Ted Lasso and Shrinking are prime examples.
I understand your feelings but I think your statement about “living in the past” is something that we all fall prey to, to some extent. Prior generations pass judgement on younger generation’s music, art, culture, behaviors , work ethic, etc.
Things change and change is constant.
I know some folks make a point of not watching the news. I just listen to old radio news broadcasts. I don't know about this ****** guy in Germany. I hope Chamberlain straightens him out.
