It's sad; despite what you say about some of them, it was admirable at the start of the 2000s when Disney attempted to try more variety at animated movie genres IE: Adventure (Dinosaur, Atlantis The Lost Empire, Treasure Planet), straight-up comedy (Emperor's New Groove), drama (Lilo and Stitch, Brother Bear, a major part of TP).
Then Home on The Range came and ruined everything.
