I grew up on this animation, and all I can say is that no classical animation-style Disney movie till date, not Lion King, Pocahontas, Hunchback of Notre Dame or any other that you can think of comes THIS close as to compare itself with this all-time classic.
A brilliant combination of wonderful voices, magnificent characters, songs that will keep you humming for weeks this is certainly the peek of animation storytelling. It doesn't get any better than this.
I give this one 10/10 without a second thought.
