17 and 19 are Team 7 versus Zabuza and Haku. It was an okay fight. It was not particularly physical or neat looking.

48 is Gaara versus Lee. Good taijutsu/choreography, and looks significantly better than anything in part 2 so far.

151 is filler...

Whoever did the Orochimaru/Sasuke, Orochimaru/Sandaime Hokage, Naruto/Sasuke fight was WAY better. I thought it was the same guy though.
