Yes on MASH and Moore and Newhart, don't know Big Bang.
Trying to remember if I liked or hated several others. I remember Jackie Gleason, et al, annoying me. I did like I love Lucy at the time. I stopped with a lot of tv, too much other stuff going on, but still liked some shows.
Was Married with Children considered a sitcom? I suppose so. I watched it, but wasn't all engrossed.
Not sure it's a sitcom as such, but I liked Frederic Raphael's The Glittering Prizes, a British series. There was at least some comedy, but also fairly serious stuff. He wrote the movie Two for the Road, if any a2kers remember that. Also a novelist and more.

I remember being intensely invested in Glittering Prizes.
There was a British series writer I loved but right now I forget the subject matter much less the title or if it was comedic. I'll noodle around in my brain and report if I remember it; I wasn't the only one who liked the writing.
