What do you guys think about nina?

She has what i call the "naruto personality"

I like the show and every character seem very well written but when it comes to nina things start to going south, even the show itself recognizes her as a walking contradiction, i watched the entire season twice and now i think nina is even more annoying than before, i love the anime don't get me wrong but nina is "very problematic when it comes to people not telling her what she wants to hear"
