Yeah, it was a good episode, but much didn't really happen. But I loved to see Orochimaru and Sarutobi fight, even I think that was just the beginning of their fight. Hmm, I guess the only bad thing in this episode was that there was a lot of not very intresting stuff. For example the rainbow and Konohamaru + his little friends stuff. After this episode I read the manga a bit again, and I noticed that there weren't any of this extra stuff.
