Roseanne (seasons 1 and 2). I hadn't ever seen it, and I know she's a horrible person IRL so I was conflicted about it, but it's just ... so much better than the vast majority of recent sitcoms I've watched. Even the trans jokes are less offensive than would be average in 2019. I can laugh with (most of) the stuff on this show rather than feel attacked. Basically I'm appalled that the spirit of this show's writing hasn't seemed to be taken up much since. It started for me with a YouTuber's analysis of the show, and even the way it was ended (originally) sounds reasonable to me. I live in hope that a spinoff where Roseanne's character is dead might be good television, but I haven't seen that yet.
YMMV. I mean, I genuinely love shows like My So-Called Life, and I've seen every season of Full House literally because I couldn't look away from the trainwreck once I started. My tolerance for late-80s/early-90s entertainment might be unusually high for a 26 year old.
