I think one of the saddest things about modern childhood is the loss of cartoons as inheritance. I grew up watching Scooby-Doo reruns decades after it first aired. Kids today have more content than ever, but perhaps less shared cultural inheritance across generations.
One of the things that still saddens me about Atlantis: The Lost Empire not being the hit it deserved... is knowing Kida would almost certainly be in the official Disney Princess lineup today if it had been.
