It’s the spinoff forced into existence by a flameout.

Starting Tuesday night on ABC, “The Conners” will attempt to stand on its own as a family sitcom without the namesake character of “Roseanne,” which imploded last May when the network fired star and producer Roseanne Barr after she posted a racist tweet. She relinquished any financial and creative stake in the spinoff, which allowed the cast and crew of “Roseanne” to carry on with “The Conners.”
