It could've also read something like "the first working-class sitcom in the US", as opposed to "the first working-class sitcom." We Brits had been at it for decades before Roseanne hit our screens!
My mum loved watching 'Roseanne'. My dad liked the theme tune!
She had a lot of cosmetic surgery at one stage, I seem to remember. I'm not arguing that this is anti-feminism (I've undergone a procedure myself by the way), but I wonder why she did it. Was it to remain acceptable in the eyes of the US Networks? I think she had facial work and liposuction.
