All of their characters on the show, with the possible exception of John Goodman, are very unlikeable.
I was disappointed the most in John Goodman for thinking the Roseanne-free "Roseanne" would work. It seemed like if anyone should've put his foot down and stood up for her, it should've been him.
He's enjoyed a long and distinguished career as an actor and will now be remembered for having zero integrity in the end when it counted.
