I dunno... Sure the NS jap fandom will be upset. And a lot of Naruto fans (neutral) will be mad for this ending.
I was lurking in another anime forum, and people in that place thought that the ending was crap and the series has been getting worse since the Pain arc. No pairings were mentioned because they did not care for them, so you do not need being a NS fan to think that the ending was crap.
The only people who are happy with this ending are those immature shippers and people who don't understand what a plot is.. they only care that their ship won and is officially canon. They don't care about the development of the characters or how it fits into the plot. The only thing they care about is winning and then be arseholes to those who don't agree.
Exactly. It is disheartening, but now NH fans are trolling LadyGt deviantart page, telling that we are delusional, we made this to ourselves, Hinata got interaction with Naruto, Kishimoto is a magnificent writer, Kishimoto created Hinata before no one else in the manga, we are just lousy losers, we chose the wrong pairing...
If NS had become canon I would never have gone to their places to trol and mock them. I would want the same common courtesy in return, but I guess that I can not hope politeness or good manners of shipper trolls.
Anyway, you are right. Many people is not happy with then ending, and they have not been happy with the series for a long time. It is not only us.
