Roseanne Barr is tearing into ABC for killing off her character. Last night's premiere of the Roseanne spinoff, The Conners, revealed that Roseanne's character died from an overdose of prescription pain pills. Barr and her rabbi said in a joint statement the death was "an unnecessary grim and morbid dimension to an otherwise happy family show." Barr was more direct on Twitter, tweeting "I AIN'T DEAD" followed by an expletive. ABC killed off Roseanne the show in May after Barr posted a racist tweet about an Obama-administration official.
