Lion King was and still is my all-time favorite. One of the few movies that can actually make me cry even now
and only movie with sequels that I also liked as well.
Fox and the Hound would be my second. Pretty sure that movie is the reason foxes are my favorite animal, too. Sequel for that was cute but wasn't really all that great, though.
Third favorite would probably be Mulan. That movie taught me how to be a man.
Top 5 honorable mentions would be:
1. Lady and the Tramp
2. Sword in the Stone
3. Emperors New Groove
4. Bambi
5. 101 Dalmations
