This reminds me that the first duel at the waterfall was probably the best battle in the entire manga.
I think the battle with Naruto vs. Pain was pretty decent^^ Yes, including the whole "Itami"-part XD
Aaand we back on the Pain fight. Honestly, I didn't mind it. I know the animation is quite bad compared to other fights and the like, but it was still fluid for how fast the fight was supposed to flow and so forth. The only times I said "Wtf?" to are when Pain went Road Runner on us and every time Pain would make a facial expression. The Pain fight and all the fights in the Sasuke Retrieval Arc are my favourite fights.
There's one fight in that Sasuke retrieval arc that I didn't like, at least not all of it. It's the fight against that Kikamaru? (the guy with the bones blood limit ability). That Rock Lee drunk monkey stuff was too stupid. But I did enjoy Gaara's entrance very much.
Funny. That's my 3rd favourite fight of the arc, behind Naruto vs. Sasuke and Choji's Butterfly Effect. (Well, those are the only fights I actually enjoyed.) My least favourite was Neji's battle because I actually have a fear of spiders. Now THAT guy was creepy. *shudders*
