While it might seem like The Conners season 6 could end by setting up a spinoff, there are many reasons that Roseanne’s re-imagining won’t take this route. The Conners has a complicated history. The family sitcom began life as Roseanne in 1988 and proved a huge hit throughout the ’90s. Roseanne was a fun sitcom about a working-class family’s attempts to get by, at least until the show’s critically abhorred final season. In Roseanne season 9, Roseanne’s family won the lottery and became fabulously wealthy in a misjudged twist that ruined the show's original appeal. The series was revived in 2017, but season 10 wisely ignored season 9.
