Aladdin, really?
I was always under the impression most people considered it the "worst" of the four ("worst" in quotations because nobody who likes those films thinks it's bad). I absolutely loved all four of those films and watched them repeatedly as a kid, but I would have probably ranked them Beauty and the Beast, Lion King, Little Mermaid, Aladdin.
As I said, I still really liked Aladdin, but I've always thought of that movie as basically just Robin Williams. He's fantastic but he's essentially the whole movie.
