The war arc was disappointing. The bad guys were not putting enough work at all. Madara and Obito is doing litteraly everything now.
-Sasori and Deidara had no jutsice and died off quick, without them using any of their main arsenal (Sasori kinda had an excuse)
-Everyone waited for the 7 swordsmen to reveal and that blew up quick. Then it died down because we don't know how good they were (never will).
-Golden brothers was pretty random to throw out in the story, just for the sake of incomplete 10 tails
-Kakuzu had all 5 hearts and still left the last mask not showing any feats (BIG WTF)
-Hanzo gets no justice, Kisi: "hey lets just block his jutsus for this battle and lose feats".
-Top Tier Akatsuki get more attention, Itachi and Pain. (We already know all their freaken feats)
What I actually liked:
Past Kage edo battles
Jinkirki vs jinkiriki (before madara)
But after that Kisi leaves 2 badguys doing all the main killing =/
