As a working-class viewer of Roseanne, its revival, and The Conners, I was struck by how much killing off Roseanne brought the show back to its roots. When I first watchd Roseanne in college, the shows appeal eluded me. The episode we studied as part of TV history, season 2, episode 8, Sweet Dreams, is something of an anomaly in the shows canon. Its an odd, semi-surreal dream/ fantasy episode where Roseannes wish for a peaceful bath is repeatedly interrupted by the rest of the family. When I rewatched Roseanne years later, the episode made more sense in retrospect.
