‘American Idol’ hoping to stay in tune
In 11th season, talent showcase has a formula for success
When “American Idol’’ returns to the airwaves tonight there will be roughly 800 singing/talent competitions on TV. Or at least it will feel that way. With vocal showdowns proliferating like notes in an Aguilera-sung vowel, what will the granddaddy of the format do to freshen things up for its eleventh season? Not much apparently. Staying the course seems to be the theme of season 11, as last year’s newbie judges - Steven Tyler of Aerosmith, and Jennifer Lopez of the block - settle into their seats alongside Randy Jackson of the limited critical vocabulary.
