Well, I mean, they fucked up.
Roseanne was always a show about white trash middle america. This makes it pretty much a Republican show. And that was always a little bit weird. They've tried to use it as a platform for something else, and it flat out don't fit. And it's not like that was a surprise. Roseanne herself made the same mistake. It's why her final season where she won the lottery fell so flat. I stopped watching that season personally, but I expect that in hindsight she might have had a few things to say about striking it rich that were probably worth listening to and probably came from the heart in some strangely distored autobiographical way. Ain't nobody wants to hear it though, then or now.
The best case for John Goodman is to refuse the pay cut and walk away.
