This. Hilariously enough at least a portion of that silly Naruto vs. Sasuke fight was ripped straight from this scene.
I thought that was Naruto vs. Neji?
Anyhow, I don't see how the Naruto vs. Sasuke fight was silly -- at least episode 133, anyhow. Annoying dialogue aside, that's one of the best animated fights in animation, period. Constant action with movement, amazing fluidity and with an individualistic sense of design.
Some other fights that immediately come to mind:
End of Evangelion - Asuka vs. the MP Eva series.
Mononoke Episode 06 - The faux-camera effect used throughout the series is at its best here; crazy sword fight that just moves about the room at a deft speed that somehow maintains clarity.
Ghost in the Shell - Motoko vs. the tank. Also animated by Mitsuo Iso, who did the aforementioned EoE fight.
Evangelion Episode 19 - Eva-01 goes crazy.
Samurai Champloo - Various episodes.
Shigurui and
Texhnolyze - Not so much for pure excitement, but how well-choreographed and grounded they are. The MMA bits with Ichise in TEX are great, and the attention to realistic detail with the sword fights in
Shigurui is phenomenal.
