Apparently, C.S. Lewis and J.R.R. Tolkien weren’t too keen on Disney’s understanding and portrayal of fantasy.
Dwarfs ought to be ugly of course, but not in that way. And the dwarfs’ jazz party was pretty bad. I suppose it never occurred to the poor boob that you could give them any other kind of music. But all the terrifying bits were good, and the animals really most moving: and the use of shadows (of dwarfs and vultures) was real genius. What might not have come of it if this man had been educated–or even brought up in a decent society?
