My son mostly likes cartoon movies over shows. Right now he's obsessed with Ice Age. I swear I've seen it a million times now. Every time he says "Wanna watch Iced Age!" (how he says it), I groan. Before that it was Finding Nemo. Now I long for Nemo after watching Ice Age up to three times a day for a month.
The shows he does watch are Dinosaur Train, Martha Speaks, Cat In The Hat Knows A Lot About That, Wild Kraztz, and other PBS shows. I'm not a fan of Martha Speaks. It's dull. Oh, and I'm not a fan of Clifford. I like the books, but the show is blah.
