Ellen Degeneres's debut on American Idol Tuesday night received much applause from TV writers and bloggers today (Wednesday). "In just one episode, new judge Ellen DeGeneres displayed why it's no stretch at all for her to step into Paula Abdul's chair," wrote Jon Caramanica, who writes the ArtsBeat blog on the New York Times website. "She was witty both in her embraces and her take-downs," he said. Andy Dehnart who writes the realityblurred.com blog, told the Associated Press that DeGeneres seemed "more polished and on-point than the people who've been sitting at that table for eight years." Fans were equally delighted with her accession to the judging seat previously occupied by Paula Abdul, the A.P. reported, noting that the majority of people posting on Twitter praised her performance. It certainly did nothing to hurt the show's ratings, which remained as enormous as ever. According to Nielsen overnight figures, 27.7 million viewers tuned in, up from the 26.2 million who, on average, watched the eight audition episodes..
