It's not "nowhere." It came out of Juugo's rear end. Team Not Seven only had a conister of beans to eat on the way...and you can fill in the rest of how this power up works from there.
Besides, being near Juugo and getting the effects of the cursed seal is not what really makes this junk. It's that the seal is "senjutsu." The concept of Senjutsu has been around for sometime, the cursed seal even longer, but only now gets around to saying that the seal is this and does so at a time where it is the only method to damage Obito.
It's awfully convenient.
The more apt comparison is to Tsunade being saved in that's it's rather contrivied. Yeah, it's kinda of an ass pull, but I don't think that's the real literary crime committed with this. Kishimoto has the villain become invulernable to all attacks but Senjutsu. The result is that no one, but a select few can cause damage (Hashirama and Naruto) him, meaning everyone else becomes support if they are lucky and plot devices or cannon fodder if they aren't. Either way, they take a back seat in the fight. Hashirama is conveniently indisposed at the moment. So, it's Naruto. But! Low and behold Sasuke can access Juugo's seal by being downwind of him and it's Senjustu (what luck!)...so Naruto and Sasuke take the lead.
They must work together in order to save everything from the pile of debris that calls himself Obito. And them specifically, rather than them as components of a larger group.
They shall fight together and briefly recreate the good old days (and Sasuke will have saving the universe under his belt when it comes to redemption time) just before they have a fundamental disagreement on how to finish saving the universe when this is over. So...pretty much it tracks the path of Madara and Hashirama point for point. And just in case we didn't get the subtle hint witht he four chapter flash back and Sasuke's current involvement, he makes sure to sprinkle in some Hashirama to turn his subtle nudging into a kick to the face.
It's terribly contrivied.
Well, yes, given that no character drive the plot as much as him, I'd imagine so. Significant changes in his behavior alter the story and points Kishimoto make.
I'm somewhat at a loss as to why this is a huge problem. I can't think of to many main characters who can be completely decoupled from the plot, especially when an author wants to make specific points using said plot.
Who here wants to see a Sasuke training arc? I'm expect the count to be somewhere near zero. It was off screen and just stated he worked really hard, who would be satsified? Doesn't expect this number to much higher.
Naruto is not immune from this either. He got his most recenet boost from a fist bump.
As if he's the only one...Sakura is a corpse if Naruto is not in the right place at the right time.
And the following is directed at the thread in general:
When did complaining about a chapter suddenly become in vogue again?
I see more than one person who lectured people last week now suddenly complaining themselves.
I don't disagree all that much with the criticisms of this chapter, but it's seems rather hypocritical.
I'm trying to put my finger on what it is about Sasuke getting these ah, contrived powers that personally irks me so much. Is it my personal bias, or is there something that sets him apart from other characters when something like this happens? I'll admit I'm far more forgiving of Naruto; I don't always think it's good writing, and I know I've been annoyed before with his training arcs, but now whenever Sasuke shows up I'm so critical XD
I want to say it's a consistency issue. I just can't understand this character anymore. Since leaving Orochimaru, fighting Itachi, and striking up with Obito, he's been all over the place. Truth this, truth that, and it's a barrage of one thing after the other when it's most convenient or as you put, contrived. It makes me sad because I really, really liked Sasuke part one and early part two (before he got a team) and now, even though he's so major to the plot, he feels lost--sort of like what James said that he's become a 'as the plot demands it' character rather than one who drives or changes the plot. It used to be about rescuing him and his revenge. He was so much more straight forward and his training was just ambiguous enough that we could imagine all sorts of things he was trained for, the power and potential he could have, and we waited for the day he showed it off. He did, with the fight against Itachi, and it was at that point he lost his original, big purpose. There was no saving him from Orochimaru, there was no pulling him out of the darkness (he showed with Team Not Seven he isn't this lone wanderer), and he's been constantly seeking the truth, only to come to the conclusion this world sucks.
Everyone else for me has been more tolerable. I know that in this manga things happen seemingly out of nowhere, but Sasuke... does anyone else feel this way about him? I'm having a hard time trying to articulate how this scene's contrivance is worse than all the others we met with. Is it because he's unsympathetic at this point? Because I'm not rooting for him so I don't care to see him grow and win?
Also, totally agree that reducing everyone else to support or fodder by making it Senjutsu only seems like a really bad move during a big war arc. Kishimoto is really bad with making a lot of people useful; he's always focusing on a few people even in big scale fights; or when teams actually mattered (with the exception of Ino-Shika-Cho, but Shikamaru was always a big focus even with them).
