Dan, I assume you're the GAF animation expert? 'cause every time I make a post about animation, you're the first one to reply.
I don't know why people treated realism as the holy grail. We have real actors for looking like real human beings, animation should use its strength and do things other formats can't do. Miyasaki does realism sometimes, they sure are impressive in their detail, but they aren't memorable because of that. Anyways, The Incredibles seem to have many serious themes. It's about family, obviously, and it seems be about fitting in, being normal, potentials and dreams, growing up and responsibility, coping with change and middle-age crisis as well. It weird the Jp trailer is called 'Mr. Incredible' though, when its 'The Incredibles' in English.
