Atlantis: The Lost Empire. I thought this was a good, very unique Disney movie. A different style of animation, a little darker, tons of violence, with deaths in the hundreds (and a funeral to boot), and more than a little sex appeal.
It probably bombed because no animals talked and no heart-strings were tugged. It did drag a little, but picked up quickly, and my only real complaint is that Michael J. Fox’s gee-willickers voice is grating.
