yeah the fight between oro and sasuke was good. yes i admit sasuke is one strong boy. but i think the best fight would be the naruto vs haku one.. i guess because it showed us the potential naruto had .. i mean at this point he had little to no control over kyuubi's chakra but to me it showed that naruto can in fact become stronger if he learns to control it (which i guess he has at this point?).
we always knew sasuke was strong and we always knew that naruto was... uh... crap? so yeah. it's just my opinion. i don't really look at animation and stuff mainly coz i can only look at the basic aesthetics like the colouring or lighting or the use of c.g.i.
