Are you retarded?
not really, it seemed he didnt have that same spark or amount of energy he had before
did you notice in part one he couldn't complete kakashi's test, but in part two he completed it without sasuke.
Thats true, Narutos training with Jiraiya was a complete waste of time, still this thread has no sense.You'd expect a legendary Sannin to teach you a couple jutsus in 3 years.
Sakura became a medic with ridiculous power, Sasuke learned kenjutsu and improved raitons.
Naruto learned how to make a bigger rasengan.
