War arc was flashback era.
A flashback here and a flashback there,even while fighting they go into cinema mode flashbacks.Chapters was mostly them.
There were some important flashbacks like obito's,minato's etc but the rest was completely unnecessary.Now i think kishi didn't have an idea on what to do.
That's how things went on from one point.
Kishi didn't think this one bit through,a bloody war is not the place for elongated flashbacks,that too for each character,sure pertaining to those important characters like villain etc then and there is alright but rest is unnecessary and was nothing but stalling.This was a clear lack of interest from kishi on the manga,wait a second,kishi-story-planning,those never come in a straight line,silly me.
