Not to mention "Don't You Worry 'Bout A Thing" for Stevie Wonder week, and "I Don't Hurt Anymore" for the 50's themed week. One dimensional? I DON'T think so.
I agree kev, Pickler did overstay her welcome.
I also have to admit a bias against the older contestants, especially those with industry experience. If they weren't "discovered" before now, there's probably a pretty good reason...
