I'd want Superman/Clark Kent to be a very wise, enlightened being, conscious, confident, a role model for everyone, because of his origin, and because Ma and Pa Kent are wonderful parents. He isn't prejudiced or jealous, and when he fights criminals he never kills (but then again, that's also Batman's thing), and he doesn't take justice into his own hands. But it seems that the film again goes for the "I don't know who I am, I don't know what I want" angle.
Superman Returns had him being depressive and jealous, I never liked that.
Superman II had him turning into a pussy after he lost his powers, and at the end, when he got his powers back, he
bullied the guy. Not something someone could admire.
