Robin Hood. Also loved the Broadway version of Beauty & The Beast.
I went through a phase when I was about 7 or 8 of being obsessed with the Disney Robin Hood movie. I even had a toy bow & arrow and a green hat with a feather in it. I found their version of King John hilarious as well.
I also liked the Rescuers and the Rescuers Down Under, Fantasia & The Little Mermaid.
But I think what I love about it, is the fact that it has dark themes and is different from your typical Disney movie.
Yeah, what makes Frollo worse than villains like scar, cruella De Ville etc is that Frollo believes what he is doing is right. That makes him so frightening.
