The rescue Sasuke arc in part 1 was already pretty terrible. The start of Sasuke's horrendous unexplained downward spiral, as well as Naruto's unexplained "he's like a brother to me!". Dues ex machinas (namely the sand trio showing up to save everyone's ass...and bone guy dying from a time limit rather than actually being beaten), characters living that had great death scenes, nothing but fights for a year, and very thin plot stretched over a year, followed by a conluding fight that sucked. (The anime fixed it some, but...) People hated it at the time, but there was still so much good will saved up from the Chuunin exams and Tsunade arc, people let it pass at the time in the hopes it would be better int he future.
People like to say part 2 was the obvious cut line, because then they can pretend all of part 1 was good. But it wasn't.





For the love god, I don't care if it's off-topic, we need to talk about Pokemon Special before we all become as blind as Itachi.
