This is one of the most painful episodes to watch. It gave nothing to the story. Half of the episode was flashbacks of the whole series! Then everyone just stands around and talks. Kakashi gives Naruto a lecture as Zabuza and Haku just stand there! It was extremely disappointing. Most of the episode made Naruto look like an idiot. Hence the title. *Sigh*
Oh well, anyway nothing happened much and it mostly was all talking. This is definitely a show you could miss. It added nothing and it gained nothing. Just skip it. Trust me. But you can tell something is about to happen, so it doesn't discourage you.
