''American Idol'': How to fix it

Something is wrong with American Idol, and here's the surprise: American Idol knows it. It's not the ratings; they're down, but after nearly six years, a plunge was inevitable. And it's not the contestants: Some past seasons may have showcased more talent, but this year's final sing-off on May 20 will almost surely be livelier than last year's Jordin-Sparks-vs.-beatbox-guy minor-league championship, or 2006's clash of the titans between Soul Patrol and McWhatshername.
