Actually, in the original fairy tale of Rapunzel, the prince had a pretty large (and somewhat tragic) role. He wasn't much of a saver either, since the witch kinda kicks his butt and wins.

I'm all for more active heroes too, but I doubt this type of hero will attract more males in the audience. I think they should go more towards characters like Hiccup, or Jim, or aladdin, as you said. This guy seems way to dashing.

I like both computer and traditional. I find both can bring out something that the other can't. Like light. Lighting is quite unique in 3D animation. However, traditional still has the more artistic edge.
