I like Muu, and believe he's not done, but I'm so dissapointed with this whole arc. I love some spots, but there is hardly any long fights. Sasori was revived and killed in like one-half chapters. Not even a big fight.
We have no idea what happened to Jugo, Suigetsu, aswell as Kimimaro's unit.
Kakashi vs the Swordsman anyone?
Kishi is rushing this war so much, that it's not good. What about Black Zetsu and the Mizukage? The old man kage vs Muu wasn't really a match. Gaara demolished his dad in a chapter. Great ending, but not fight.
I had hopes and defended the war at the beginning, but overall, it sucks. It's full of big spots and great endings, but they happen WAY too fast and are speeding over other things. I still love Naruto and will read the war as always, but I'm dissapointed.
I hope and believe the animators will make it better by adding in more fights.
