Anything is better than some of the overly sugary crud they turn out for 'children's entertainment' here in the US. I remember when adults could be entertained by cartoons, too.
Interestingly enough there's a fair bit of quality children's TV around at the moment. There's Horrible Histories (which is easily one of the best comedies around), plus lots of comedians are making children's shows, because they can do (silly, daft, fantastical) stuff they can't on regular TV.

Indeed. I read in an into to an anniversary edition of A Wrinkle in Time that Ms. L'Engle had to keep telling her editors that when they wanted her to dumb down the science parts of that series.
Why am I not surprised?
