The fact that it lasted two days (not even, I think) is ridiculous. Kishimoto failed in delivering the sense of war. There was no despair, no terror, no nothing that could cause PTSD or something. The only sense of despair I got from the alliance was when Madara decided to throw down a meteor.
Comic relief just doesn't fit in with a war. Should've been kept to an absolute minimum, or nothing at all. (this goes for the anime even more, with its stupid fillers that destroy the vibe that was hardly there in the first place.) Being a shonen manga is one thing, but having a war being fought by teenagers whom seem hardly bothered by all the death around them is stupid.
