1) Sleeping Beauty
Aurora has always been my favorite Disney princess, despite saying very little in this movie at all. She just has the best singing voice, okay!?
2) The Secret of NIMH
This movie was a staple in my house growing up. It was darker than most Disney films, and for some reason most of my friends had never heard of it, so it felt cool to me.
3) InuYasha: Swords of an Honorable Ruler
Alright, I feel like I can be honest with you guys. I don't watch a lot of anime, but I have this weird obsession with InuYasha. When I was in high school, it was on Adult Swim every night when I got off work, so I'd watch it and do my homework. Then I got really into it. Someone was uploading the manga on photobucket, and I read it every week. I've seen every episode. Now, the movies they made were so so at best, but this one, the 3rd one, was actually really fucking awesome.
Honorable Mentions: The Last Unicorn, A Bug's Life, The Land Before Time, The Hunchback of Notre Dame, Hercules, Tarzan, Sampson and Sally, Spirited Away, All Dogs Go To Heaven and The Black Cauldron.
