The Lion King tops my list. However, Gargoyles is worthy of a mention in terms of TV. And all of the Disney-Pixar have been stir fried awesome, though Cars wasn't quite up to the level of the previous Disney-Pixar movies. The Incredibles definately tops my Disney-Pixar list.
Favorite animated movie would be Shrek, but that's Dreamworks...then Incredibles, but that's Pixar (does that count?? Not really...) I guess I should go traditional animation. I'd say either Lilo & Stitch or Mulan FTW.
