Blues clues is actually one of the better ones. It appeals to kids and talks to them in the same way they themselves think. It is the age of imaginary friends and magical explainations. The biggest problem with childrens shows isn't the ones with imaginitive programing but the ones who stick adult subject matter in or treat them like they're stupid and use absurd solutions to everyday real situations. Children learn what they see. What are they teaching them?
...and yes, I can't stand Barney either.
