What sucked really hard in the end - Kishimoto's attemps of neglecting NS pairing/moments/bonds that it's could be seen as WTF? chapters, there wasn't even chapter when Naruto and Sakura was not bothered by something and didn't interact at all. Whole part 2 was about how both of them grew up. And what now? They don't even interact.
Naruto, main character got 1 line in chapter 699. It's his goddamn story, his ending. His story wasn't resolved at all. Frog Sage wasn't even mentioned with his prophecy about child. Naruto's POAL to himself/Sakura - didn't get resolved even in one panel. Sakura, his kittening LOVEINTREST that was there whole time, what manga did you read ever when MC and his loveintrest not only don't have resolve of any kind in the end, they don't even interact in any way with each other! It's not even close to be resolved. He didn't confess, nor he got rejection by Sakura, literally nothing, because again... THEY DON'T EVEN INTERACT IN LAST CHAPTER! And whole story of Naruto didn't get any closer from his POV, great. Oh... and did Naruto became hokage? Did we saw how all his friends cheer for him? How he smiles when get a Hokage hat on his head? NO, because in whole story NARUTO didn't even succed in his 1st and main goal, kittening epic win of manga! He got his main goal handed to him 5+ years after manga ends, offscreen. Bra-kittening-vo!
Sakura, main heroine of story, get demolished, with sudden attack of amnesia, that line "sorry for what?", like okay... You loved him, he proclaimed that he would kill your teacher, he literally killed you several hours ago in genjustu, before that, he didn't even tried to save you from dying, didn't care about your wellbeing, and being totall a**hole for 2 past years. Like - let's forget that, how about your friend right here, that lying half-dead without hand, who tried to stop Sasuke. Remember him? That's Naruto, the only person that supported you every time, and that person just tried to kill him and now you saying "sorry for what?". And second part of her when she turned 12 years old herself from chapter 3, and all her development from the start (including feelings for Naruto, goes out in the window) don't even worth of mentioning it.
Sasuke, who's main role was to be RIVAL of main hero, what is his ending? It's one of the best endings any villian/bad guy can ever have. After previous chapter of with his revelation, now amost whole chatper of his POV. In the end, he forgot that Konoha killed all his relatives, and didn't even mention something about honoring Itachi's sacrifice for piece. For all he done so faw, he only apologise to Sakura, and as it looks like - for nothing in particular.Then he suffer no punishment for his deeds at all and even knowing about Naruto's feelings for Sakura, Sasuke gives her some hope with he's poke to her forehead and he lives village to become vagabond, forgeting that 5 chapters ago he wanted to change the world and unite all people. And yet again he neglecting team that he gathered himself again. What has been changed in Sasuke since he went out of village in part 1? His motive for living those few who cared for him? Well, at least last chapter of NARUTO was about SASUKE.
So much for "conclusive" ending and characters OOCness development
