It depends though, if the character is still interesting, I don't really mind.

Agree with dimitri_

Rapunzel is too perfect, but she's still a very interesting character.

Why would a Mary Sue bother anyone? Haters.

It used to really annoy me, but now that I understand the importance of context when it comes to a character's apparent Mary Sue-ness, it doesn't really bug me anymore. I'd be annoyed if they were flat and lifeless, but Belle and Rapunzel for example, are still full and well rounded characters.

I bothers me a bit, but not to the point where I automatically hate them. I just don't like how they have no negative or in between traits and how everyone praises them and they have no conflict in their lives. As long as they are interesting but if they are perfect, they do have less of an impact on me, which is why I never cared for Rapunzel and Belle dropped a lot of places on my list.

Not really

no such thing

Well, I mean, it does a bit, but I usually have stronger issues with characters that turn me off

I honestly don't think either of the Princesses are "too perfect", they all have good points and bad points.

Slightly...

Better too perfect than too flawed imho. I tend to prefer Sue-ish protagonists over very flawed, anti-heroic ones( although I DO like protagonists with some flaws, I don't like very flawed ones like Tulio from Road to El Dorado.

BTW, I'd use Ariel&Jasmine rather than Ariel&Pocahontas for "yes" option. I'd Pocahontas is close to " too perfect"(and is my favorite DP).
