The evolution of Roseanne's parents
Between "Dear Mom and Dad" in 1989 and the course of the rest of the series, the friendly, happy man everyone was happy to see turned out to be an adulterer who had abused Roseanne and Jackie when they were kids. And we all know how Bev evolved over the years.
They were not the same characters in "Dear Mom and Dad."
I've never been a big fan of the first season.
