Okay--I know nothing about scripting for animation, so the only advice I can give is from a parent's perspective. PLEASE -- don't make the feature longer than 75-80 minutes! Let's remember who our target audience is...children. Attention span = hardly none. If your movie is GREAT, you can hold them for about an hour before they get antsy (depending on the kid, of course). By 75 minutes, the kids (and therefore, the parents!) are ready to leave. The Incredibles, which runs at about 2 hours, was just brutal. Someone needs to tell Pixar that, no matter how good their movies are, they need to come down off of that high-horse and remember they are making movies for children.
