To be honest, I liked this chapter by taking it as a self-contained one. It had the vibe of peril and despair that the travesty of the Fourth War lacked. I'd take Naruto's messiah prophecy bullshit seriously if this was what happened from chapter 400 and forward and not the fake slaughter of Invasion of Pain or Kishi finally killing characters when the war is fucking over via the hilariously bad eldritch abomination. And I did like to know that there were more siblings of both Madara and Hashirama, it makes them more human and bitchslaps the fantards for thinking Senju and Uchiha are somehow infallible.
Now, taking into account the sequence the chapter came from, I have to agree with LN: this is just milking the shit out of these two characters by stepping on the dragging pedal and the flashback was poorly done. It seems Kishi doesn't know how to pull in media res.
So, taking everything into account, it's a good chapter that only suffers from its framing.
