While The Conners made it seem like one Roseanne star didn’t have long left, season 6 of the spinoff has proven that this might not be true. The Conners has a complicated relationship with its predecessor, Roseanne. The sitcom began life as a revival of that ‘90s hit, bringing Roseanne and the Conner family back to screens after almost two decades to see how they were faring. However, when star Roseanne Barr was fired for racist tweets, the show’s title character was killed off and Roseanne became The Conners. This made it tough for the show to bring back old stars.
