Definitely.

ABSOLUTELY! I'll comment later to explain why because I have such a headache right now.

I don't really see Odette as a bad one though. but then I'm too blinded with nostalgia to really look fairly ;)

I've already said this in a different pole, but thought I might as well copy-paste it here.

Odette has a lot of traits in common with classic Disney princesses, but she is also quietly brave, willful, and competent. She doesn't openly defy like Ariel, raise her voice like Jasmine, sing of her discontent like Belle, or dream only of finding love like the classics. She is classy, polite, soft-spoken, and all that good stuff, which is great for kids who see themselves that way and thus can relate to her more - but she also won't let anyone take her for granted or push her around when it really counts.

When Derek suddenly decides to marry her after a lifetime of fighting just after getting a good look at her, she asks very softly but earnestly: "What else? Is beauty all that matters to you?" She doesn't berate him as Jasmine berates Aladdin, but she also wants an answer. When he can't answer, she's clearly disappointed and heart-broken, but stands by her decision not to marry him until he can. When her father asks later, she says, "I need to know that he loves me for just being me."

When Rothbart later kidnaps her, she has hit ROCK. BOTTOM. Her father is dead, she's whisked away to a ruined castle in a far-off kingdom, cursed to be a swan during the day, and fixed so she can't leave the lake if she wants to be human again, and it seems like the only way to lift this curse is to marry the jerk that did these things to her. Her answer?

Odette (softly): Every night, you ask the same question. And every night, I give the same answer: I'll die first.
Rothbart: You know, you're really starting to bug me.
Odette: I should think you'd be used to it by now.
Rothbart: That's it! Just keep pushing. One of these days, I'm going to BOIL OVER!
Odette: Go ahead then! But I'll never give you my father's kingdom!

This is a woman who stands by her convictions and doesn't waver for a second, yet remains kind, gentle, soft-spoken, and ladylike for those girls who relate to it more. I think a princess who questions the idea of falling in love and getting married based on looks alone is always a good thing, and a girl who stands by her convictions and doesn't let people push her into something she doesn't want or isn't ready for, even without being loud, abrasive, and rebellious about it, is always worthwhile.

P.S. I'm not saying any of the other Disney heroines or personality types are bad. It's just that different personality traits appeal to different people, and you don't always see very quiet, gentle, soft-spoken, ladylike women have such strong convictions or an indomitable will.
