what i like most is it appears to be long range (finally naruto has a long range attack) and that he doesnt get worn out from it.
One final thing about "that jutsu"
when chasing deidara naruto gets pissed off at the fact that deidara cant be attacked as hes a long range fighter, and naruto states he has no long range attacks and kakashi deals with it.
Naruto was in a very pissed off and emotional state, and knowing narutos personality we all must know and admit if he had a secret long range jutsu, he would have used it, or at LEAST said "no, jiraiya said i couldnt" or something, but not a peep.
Im with the guys who say it was mistranslated.
it appears to rasenshuriken buffed up with sage mode.
P.S. Its called rasenSHURIKEN for a reason, chidori is the same as rasengan in that its a move you simply drive into the enemy, and even a genin like rock lee noticed how easy it is to dodge them kind of moves.
Rasengan needs to be long range, especially against these new guys, i still reckon kakuzu was too easily defeated, he had 100+ years of experience and craploads of skills and talent and 5 elements, and all it took was 2 tries of a kage bushin trick.
Akatsuki is not meant to be that stupid or weak, lets admit facts, thatd never have worked against itachi, deidara, sasori, orochimaru, kisame etc etc
especially madara and pein.
Kakuzu and hidan appeared to be the weakest ninja in that they got hit a lot, most other akatsuki are almost impossible to attack, let alone kill.
even granny chiyo who knew sasoris moves took ages to finally land an attack, orochimaru just never gets attacked, and when he does he vomits imself out again, deidara only got ht by gaara and kakashi, one at kage level and the other near kage level.
Itachi was playing around, way too fast.
the rasengan is difficult to learn, 4 years for the rasengan, and its hit rate is very small, not worth it to be honest, unless its going to be perfected somehow.
