I'm more disappointed that nothing spectacular happened in the 600th chapter. That's a pretty big milestone, even when you consider how shit the manga has been as of late. Instead, we get half flashback, a confirmation that we didn't need, and an unwarranted escalation. Everyone was getting beat by Obito rather soundly, and now that Madara's in the mix, nothing short of deus ex machina is going to save them. And yet, we all know how it's gonna turn out:
Naruto and company are gonna get beat up a lot, then Naruto will say some vaguely inspiring shit, then everyone will get pumped WOO YEAH YEAH WOO and beat up the Uchihas enough to make them retreat.
Where's the tension in all of that?
