Another Arthur fan here. I grew up on the books, and I like the cartoon. Even though I don't watch it as much as I used to, it's still pretty good to watch whenever I seem to catch it.
Then there's Dora the Explorer. I think it's a neat concept to teach little kids Spanish at a young age, even if it is repetitive from time to time, but hey, I have little cousins I watch over that like this show, and I'm willing to watch it with them.
