Something you guys hating on Kaguya have to remember...
Kaguya wasn't a ninja! One of the most important morals that the Naruto manga has to offer is this:
'It's not about how big or powerful your technique is, it's how you use it.'
So you had Kaguya, 'creator of all chakara' pitted against ninja. Kaguya wasn't around when Ninjutsu was invented. She didn't train to be a ninja, so she had no tactical skills or wide variety of advanced techniques. Her skills amounted to:
1. Shifting the dimension.
2. Sucking up chakara.
3. Using portal gun.
4. Shooting death spikes.
She wasn't a fighter, she didn't have skill or strength on her side in a fight. She was just a giant ***** who could amass and control a bunch of chakara. That's why she was sealed so easily. You had 4 of the most talented and skilled ninja in the story work together to deceive and seal her.
Then there are those of you who keep whining about how the war arc was terrible. First of all, the story has gone through so many plot twists to get to this point, you can't help but appreciate the genius that went into them. Sure, the whole arc might seem a bit cliche (world's destruction threatened by bad guy who gets defeated), but that's the only place left for the manga to go (outside of fan service like Naruto + Hinata/Sasuke + Sakura hooking up).
Literally, the entire 500 chapter 'Naruto Shippuuden' series has been building on this massive plot to steal all the bijuu and use them to enslave the world in infinite tsukuyomi. The only logical conclusion to the manga would have been:
1. Everyone is enslaved, manga ends.
2. Infinite Tsukuyomi is somehow stopped, manga ends.
This is a story about a hero who saves everyone, so I don' think Kishi ever planned on ending it by everyone being stuck in a genjustu. There had a be a defeat of the main bad guy, and it's happened. You people should be grateful.
Some additional points:
1. Madara looks dead. I doubt someone who had his body taken over would be alive after that. Obito was barely alive when he had the Juubi removed. Only reason he stayed alive was because Naruto saved him.
2. We still have to catch up with the 5 Kage, everyone who is stuck in the Infinite Tsukyuomi, and Orochimaru.
3. Even after the war, there is still massive devastation across a wide area of the ninja world.
4. I can see Kishi spending the next few chapters wrapping everything up. I'm not sure if there will be another Naruto series after this, but I can see Kishi doing it.
