The mid-80s to early-90s was arguably the best era for solid television sitcoms. While my 1980 birthdate probably makes me a tad biased, no rational American can argue that this period was not the best for fictional TV lands.
I want to be excited about a new blue-collar sitcom starring Roseanne. But as it stands, I'm not optimistic. It's not that I don't have faith in Roseanne: on the contrary, I place most if not all of my faith in her. But I've been let down before.
