Off topic, but I am exposing old favorite shows to my kids while we're all shuttered. The ones you mention here are on that list, along with countless others. I have to say, some of these classics just don't hold up well. I won't name the worst performers, but the surprising poor performer was M*A*S*H, with the surprising thumbs ups being Brady Bunch and Frazier.
I guess this isn't off topic: You know you're old when you watch one of your favorite shows from your youth, and all the actors are dead.
