Task: Question Generation
Input (English): Some of the later writers about the show were more positive, Michael Slezak, again of Entertainment Weekly, thought that "for all its bloated, synthetic, product-shilling, money-making trappings, Idol provides a once-a-year chance for the average American to combat the evils of today's music business." Singer Sheryl Crow, who was later to act as a mentor on the show, however took the view that the show "undermines art in every way and promotes commercialism". Pop music critic Ann Powers nevertheless suggested that Idol has "reshaped the American songbook", "led us toward a new way of viewing ourselves in relationship to mainstream popular culture", and connects "the classic Hollywood dream to the multicentered popular culture of the future." Others focused on the personalities in the show; Ramin Setoodeh of Newsweek accused judge Simon Cowell's cruel critiques in the show of helping to establish in the wider world a culture of meanness, that "Simon Cowell has dragged the rest of us in the mud with him." Some such as singer John Mayer disparaged the contestants, suggesting that those who appeared on Idol are not real artists with self-respect.
