Roseanne showed some hard reality but no, I don’t consider on the same level of cynicism over right and wrong. Despite all the bickering you knew everyone wuvved each other.
I’ll give you Married with Children.
Jason Alexander has a pretty good take on Seinfeld’s innovations to sit-coms:
The dopes on Married With Children were obnoxious, but they were not evil and they certainly did love each other. Al was ‘sold’ by Peg to Jessica Hahn in one long-ago episode, but he couldn’t go through with it. He did shed a tear when she left the house in her whore-ish getup, but he loved his Peg. And he defended his family, over and over: ‘Let’s Rock’.
Whooooahhh, BUNDY!
