'American Idol': David Cook's Journey

At least we got a look at a pair of legitimate Top 24 prospects tonight, via Samantha Sidley and David Cook. David's personality occasionally seemed limited to the red highlights in his bangs and his argyle sweater vest, but he changed up Bon Jovi's lamebrained ''Livin' on a Prayer'' with such languid beauty that I'm itching to hear what he'll do if he advances to Idol's big stage. —Michael Slezak, Jan. 29, 2008
