As usual, I disagree with most of you about the quality of this episode. I thought it was pretty good, with good action and some story progression.
I didn't like the switching between fights, especially since not much happened in the Itachi/Kakashi fight. I know it's his character, but impetuous Naruto gets old fast, and you just want him to shut up and sit still, considering that when he does act, he gets caught in a genjutsu so easily. Also, all 3 of Gai's pupils attacking the same way and getting caught in the same trap was hard to believe.
New techniques for Neji was cool. Gai taking Kisame's sword was beautifully done as well. Tenten warning Lee and Neji about the big ass wave coming straight for them was stupid, followed later by Lee warning Gai and Tenten about the big ass wave coming straight for them. I guess they didn't see it coming as soon as Lee. Chiyo having to explain 2 on 1 fighting to Naruto was freaking stupid.
The preview was hilarious, with the watershow announcer analogy. Sounds like a typical Japanese commercial with lots of hype and exclamation points. Plus, it showed Gai using nunchakus! Too cool.
