It was a weird reaction to 'Batman Returns,' because half the people thought it was lighter than the first one, and half the people thought it was darker. I think the studio just thought it was too weird - they wanted to go with something more child- or family-friendly. In other words, they didn't want me to do another one.
I've often been accused of, 'Oh the movies looked good but there's no story,' but I disagree with that in theory, and '9' is a perfect example for me because the feel, the texture, and the look of that world, and those characters, is the story. That's a major component of why you feel the way you do when you're watching it.
Working on 'Nightmare Before Christmas,' I had endless arguments, like the studio saying, 'You can't have a main character that's got no eyeballs!' 'How is anybody going to feel for somebody with just eyesockets?' You know? So, it's those kind of things that really wear you down.
