I do have to say that I'm a bit impressed with Kishimoto's idea of having his audience enduring the extended flashback to mimic the journey of Hashirama, but I wonder if that's actually intentional. For week after week, we had to watch as Hashirama put up with all the mood swings of Madara Uchiha but still offer him a hand. It seems that even the First Hokage has a limit to his generosity. I'm not sure if we'd have appreciated that change if we hadn't seen everything he had to put up with.
You just can't miss the humor in the fact it took Kishimoto eight weeks and seven chapters to basically tell what he sums up in the final panel of this chapter. It was a nice trip, it could have been a touch shorter, and it still doesn't make up for the lame pee joke.
The concept of change is heavy in this final chapter. Hashirama has a solid character arc. We understood how he endured and changed, but Madara's mood seemed to change with the wind. We don't even understand his motivations for what would become their final battle. Though, I'm not under any delusion that it would be any more rational than the other things he's done. I now find him so childish that I don't see him as a threat. That's not great for what's ultimately the puppet master behind Obito.
I actually took a few minutes sitting in my living room after reading this chapter to contemplate my rating. I wondered if I should include my level of pleasure in seeing this flashback coming to an end to the calculation. It's nice to finally see the culmination of Kishimoto's vision with this flashback. While I have a new appreciation for the creation of the Leaf Village and Hashirama's growth. I also came out of this with a sheer level of annoyance for both Madara and the Uchiha in general. The chapter has the content of a 3, but the payoff is what makes this a 4 to me.
