YouTube brought me here :lol
And I agree with you on one thing and disagree in another...
I agree: Izanami. Asspull of the year.
Disagree: One of the things I liked the most about Itachi on that battle was a trait that many people forget: His empathy. The whole Izanami ploy was also Itachi trying to redeem Kabuto, someone who he identified with his old self.
So to me personally, I would liked to, after the canon fight, after seeing the Bros managing to survive everything he threw at them, Kabuto having a mental breakdown, whitout knowing who he is... And Itachi comes to him, talks to him, forgives him, and convinces him to dispel the Edo Tensei. It would be exactly like canon (with Kabuto replacing Oro as the one who summoned the Hokages with the knowledge of Suigetsu's scroll), Kabuto would have been redeemed and fit within the story...
