To add what I posted elsewhere days ago:
It's that personality of hers, the fact that she's still in love with Sasuke, and the fact that she's supposed to be a main character. Expectations are higher for her as a main. Take her off the posters and DVD covers and make her a side and she's awesome.....oh and lets not forget the false confession. I think that;s what REALLY got ppl hating her.....that and her wondering who she'd save first in the anime.....
I blame 70% of her haters on the anime.......take a poll and I'd bet money most of her haters watched the anime first......they took all kinds of liberties with her thoughts, dialogue, and personality that made ppl hate her....IMO..
..oh yea and the false starts.....every time you think she's about to do something cool she disappoints you.....i.e., killing Sasuke to relieve Naruto's burden....in the end, she chose to leave the burden on Naruto's shoulders when she couldn't bring herself to kill Sasuke ,effectively choosing Sasuke over Naruto......
.......and lastly, ppl hate weak *****es and dumb *****es.....she's perceived as weak in comparison to the rest of team 7 bc in battle mangas, strength is respected above all else (unless you have some other noteworthy quality or you're an underdog in which case ppl cheer you on.....Sakura was pretty much an underdog but she the fact that she thought she was the shit and acted like she was better than Naruto while not dong sh*t lead ppl NOT sympathize with her).....
...she's perceived as dumb bc after all this time she still loves Sasuke. Ppl hate that shit even in the real world. How many ppl criticize and develop contempt to a degree for women who stay in abusive relationships (for example)....or women who choose the bad guy over the caring sensitive guy.....ppl hate that shit.....and of course the fact that her being "in love" with Sasuke makes ZERO sense. He barley even talked to her. She knew nothing about him. Kishi should've written this off as a childhood crush ages ago.
I guess he's trying to correct that now with Kakashi saying her love if different and she just wants to save him from darkness. SAVE him? Really? ***** gave up on him and was getting ready to kill him. SMDH.
