1. Sarada and Hanabi are connected to the Otsutsuki clan.
2. Hinata's personality isn't unique and is hardly noticeable, she's merely too quiet and shy to really voice who she completely is personality wise.
3. Hinata is not the only female character with a good background, Konan's background is far more interesting and heartbreaking. Hinata just sucked at doing her job as an heir, that story is utter dribble.
4. I'll admit, she was the first to acknowledge Naruto.
5. Hinata is not the only female with a direct connection to the Otsutsuki. Any female born into the Uchiha, Hyuga, Senju, Uzumaki, and Kaguya clan are born with a direct connection to the Otsutsuki.
6. True she didn't chase after Sasuke, but had Naruto left she would have chased after Naruto so I don't see how this even matters.
7. Her making her own technique doesn't make her stronger or more unique, anyone can do it.
8. Sure she has memorable quotes, that cannot be denied.
9. Her being a princess means nothing. The Otsutsuki clan that became the Hyuga clan is dead, and Hinata was simply named that for the sake of giving her more status and relevancy so her marrying of Naruto would seem more groundbreaking.
