I'd rather a million Elmo-centric Sesame Street episodes than even one episode of Barney or Caillou.
That said, every kid needs some old-school, Elmo-free Sesame Street and Mister Rogers. (No, "Daniel Tiger's Neighborhood" is not the same; it's insipid and dumb by comparison.)
Also, back in the day, Square One TV had a police-procedural parody called Mathnet that was still loads better than network TV's attempt at a mathematical-cop show for adults (Numb3rs).
It literally couldn't get any better for a kid than PBS in the 70s or 80s.
