I have to laugh a little, since that amazing hair in CGI is SO HARD to replicate realistically. Just watch the special features for Incredibles to see all the trouble they went through to program hair that would move realistically. Computers do make things look pretty, but it's a lot of hard work to make things move realistically compared to just being able to draw things moving realistically. We've not seen anything like Pocahontas' hair in CG movies. Think about it. ^_-;

I do think that any movie could and can be made traditionally. All that computer animation holds over it is more dynamic camera angles and realistic renders.
