i dunno if you guys thought much about it.....but it kinda bugs me how kishimoto adds things into the series that seem like it would be a really big deal.....and maybe for a while it is, but then you find yourself in a wtf situation and wonder why he bothered with all that
i can think of at least 3 occurences of this.....
1) oro putting the seal on naruto
Its supposed to mess up naruto's flow of chakra with kyubi....but how did that actually impact the series in any way? I guess it got jiraiya's attention....but it seemed a little elaborate of a way to do so....naruto was still able to perform just as well in the prelims with the seal, and im sure if he actually had chakra problems, he wouldve pointed it out as anime series tend to do so.
2) gekkou hayate's cold
Rarely do you see an anime character distinctively coughing alot without there being a purpose to it. Some thought maybe he incorporates his cold with his jutsu or something weird like that. Considering that ninjas can use bugs for combat, why not germs? Yet instead he just dies and nothing more is said of it.
3) sarutobi sealing oro's arms
Ok now im sure i'll get some arguments about this one....but if all oro had to do to regain his arms was to use his immortality jutsu....sarutobi's death was completely in vain. All it did was delay him, which in itself may be enough to change the outcome of the series, but unless something big happens within the next few years that oro has to wait before performing the jutsu again, i'd be pissed. I'm sure this was all part of kishimoto's plans to have sasuke join oro without being possessed too soon, but for someone as prestigous as the hokage to sacrifice his life just to buy them 2 years or so seems kinda lame.
