I think my main problem with kids shows are that half of them are so PC and go so far out of their way not to be offensive or scary that they become utterly void of any feeling or wonderment. The other half try too hard (and generally fail) to be "edgy" and "hip". There are exceptions but not too many.

The few somewhat current kids shows that have been fun have been Courage the Cowardly Dog, The Grim Adventures of Billy and Mandy, Old school Dexter's Lab, Fairy Odd Parents, and Pucca. Other shows worth noting but I have a hard time categorizing them cause I disagree with calling them "Kids shows" are Samurai Jack and Avatar: The Last Airbender.
