Not sure why everyone is going off saying this is a good episode. I mean... it was decent at best. The overused animation of Gaara getting Shukaku sucked out of him was annoying, there was a lot of running between the teams, and then there was a little too much shock factor involved with Itachi. I mean, was it really necessary for Naruto to say his name, then have the animation pan over to Sakura saying the same thing, followed by a zoom in of Itachi's face?
Plus, they did a terrible job of Gai-sensei's forgetfulness. In the manga I laughed, because I think it was intended to be funny. In the anime, they continued to play dramatic music, and there was nothing really funny about Gai not remembering.
Still better than the fillers, though, and that god-awful excuse for an anime movie known as Naruto Movie 3.
