Dude... *sigh* nevermind... they are computer generated. It's from a teaser video shown during TGS. It is very doubtful that it is in-game, though.
The
fight was the one. I remember being annoyed by the other one you listed because too many lame techniques were being used. It is well-animated though and deserves mention.
No... just no. I started watching some of your selections to see if maybe I was remembering wrong, but I was correct in my recollection (BTW amv creators all need to just choke on the crap that they consider art. Playing Evanescence over a clip of Naruto is stupid and requires zero talent or skill. It also makes it damn near impossible to search for anything anime related on youtube). I stopped because it became apparent that you and I have very different ideas of what's good. Take the Neji/Hinata fight. I didn't have to rewatch that one. I remember them using the same frames over and over again. I think the Kimmimaro and Rock Lee fight was part of the filler that I watched. It was like DBZ all over again. Use two frames of animation and say they are fighting at super speed.
