Can't think of many cartoons I hate, I think because I've never been too fond of tv, so cartoons became my favourite form of escape when I want to... get away from my thoughts for a while..
Wait... there is one I definately don't like...
Astroboy, in my memory as a child it was so amazing and creative, I saw it a few years later and couldn't believe how cheap and nasty the voices/animation/story/EVERYTHING was.
Hmmn what about kids shows we love?
I love avatar, evangelion (not really kids show but eh), rocko, ren n stimpy hmmn
ren and stimpy, now that was one educational kids show!
