For many viewers, the 2 3/4-hour full Disc Two (The Worst Of) will likely be the favorite. For it is here that the set focuses on our fascination with the profoundly clueless, those utterly untalented folks who make us squirm with their outlandish self-delusion and willingness, nay eagerness, to humiliate themselves on TV (epitomized by William "She Bangs" Hung 2:42:48, the so-bad-he's-good sideshow that's depressing on so many levels), only to then find themselves genuinely astonished and angry when they fail to make the cut.

If American Idol has a dirty little secret (aside from Paula Abdul's personal life), it's that the show hasn't produced a single artist with not just a good voice but an original one--a Norah Jones, an Alicia Keys, a John Mayer, someone can play and write as well as sing. But then, that's not what the show is about; we're frequently reminded that this is "a singing competition," pure and simple. Which brings us to what may well be this exhaustive (and perhaps exhausting, too) set's defining moment: When a particularly awful "singer" begs to do another tune, Simon Cowell says, "There's only so much punishment a human being can take." Replies the contestant: "No, I can take a lot more." Randy Jackson is the third judge.
