Disagree. Because what did that do for her character? NOTHING. So she would have stayed the same whether she confessed or not. DO you see any progress for her character beyond that point? she was only telling the one person oblivious to her feelings within their fictional universe and beyond the fourth wall, to anyone that gives a kitten and it still amounted to nothing. And I repeat again. NOTHING HAPPENED. The so called target of her affections didn't get the hint even in the movie her wankers/fappers/self inserters/ male self inserters to scumzamaki are so proud of to call canon cause she got what she wanted and by extension themselves. Naruto didn't notice her her more than usual. He didn't interact with her more than usual. He didn't feel anything special towards her, as usual. It literally took over half the movie for him, with his own "so-called friends" stupidly playing matchmaker for him, a genjutsu guilt trip, and a rivalry with a kitten developed, half-a$$ed thought out villain to take poor sweet Hinata out of pity, and because of his rejection from Sakura. Did I miss anything else?
Probably but only because the movie is that bad.
