Atlantis: The Lost Empire. A time when Disney's was allowing some free reign in the movies being made. It's so good, I tear up every time (or maybe that's the emotional disregulation).
Titan A.E., a fantastic space/action flick during the early years of hand and computer animation mixing. Absolutely kick ass soundtrack. Featuring Don Bluth's boyfriend. XD
Meet the Robinsons. I think this falls under "Cult Classic" for a Disney film, because I generally don't hear a lot of people talk about it. Computer animated, wonderfully silly, very touching, and surprisingly encouraging without being too heavy handed, like a lot of Disney can be.
Honorable mention: Wreck-it Ralph.
Two words: Choke. Hold. I saw it in theaters three times.
