The Thief and the Cobbler is like the Yngwie Malsteem of animation. Extremely impressive, masterful, and technical, but a little lightweight on the emotion and storytelling.
Fantasia, on the other hand, is like Jimi Hendrix. Extremely experimental and colorful.
Pinocchio, I would say, is like Brian May, full of passion and emotion and grandeur.
The Lion King is B.B. King- soulful and emotional, yet fundamentally simple.
The Secret of NIMH is Robert Johnson- raw and bleeding, yet masterful.
Who Framed Roger Rabbit? is Brian Setzer. Madcap and old-school!
