Good TV Shows for 10 Year Olds

It is becoming increasing harder to find good TV shows for a 10 year old to watch. I find all the Disney sitcoms - "Good Luck, Charlie", "Wizards of Waverly Place", "Suite Life on Deck" and others - to have bloated caricatures of kids. They seems to be very superficial, materialistic and overly simplistic in their humor but with much exaggerated display of emotions. “Phineas and Ferb” is pretty good, but that is it. Nick, Jr. shows are too “kiddie-ish” and regular network shows are too mature. Does anyone have suggestions??
