I'd mostly agree with you except the last line. She's been seriously underestimated as a character.
Problem with Hinata isn't that she's completely weak, it's that she has no actual feats.
Look at Hinata's opponents :lol
Neji - Prodigy, at that time he fought Hinata, he would defeat Sasuke as well.
Pain - LMAO.
Hinata needs to fight a shinobi on her level, then you can accurately judge her. But compared to Sakura whose supposed to be a Neo-Sannin? You can't insert 'Hamura's chakra' as if that gave her some incredible Rikudou boost to fix the gap of power. Especially when the Last didn't showcase any new powers to even assume so.
The only thing Hinata has over Sakura, is straight out Taijutsu. The only thing the Last gave her tbh, however that's clearly not enough.
Boruto already admitted Sarada was better at ninja feats than him and she didn't have someone to teach her Uchiha techs
He never said anything like that. In the Novel he did mention that he wanted to be a Ninja like Sarada because she doesn't give up so easily, though, the Novels aren't canon.
But if you're talking about the Movie, I've watched it about two or three times. So I know my stuff and don't have to double check.
