While The Conners season 6 could technically bring back Roseanne’s titular heroine, this would be a terrible idea for the spinoff. Roseanne was a popular sitcom throughout the ‘90s until the show's ninth and final season. When the series was revived in 2017, Roseanne season 10 immediately retconned all of the critically abhorred season 9. The Roseanne revival was popular among audiences and brought back many of the memorable characters that made the original series so successful. However, Roseanne season 11’s existence was jeopardized when series star Roseanne Barr tweeted racist comments about Valerie Jarrett, a former advisor to Barrack Obama.
