this was one of the best episodes ever!
i have to admit that there was just very little action, but still the animation and details (story/character design/movement/shadows etc.) were so good that i enjoyed it more than 95% of the other naruto-episodes...
and it was very funny too... and man, is it just me or does someone else think that naruto starts to get somehow skilled.. until now i always thought about naruto beeing a 12 year old but in this episode he looked cool... so did sakura too..
the Root-Anbu who talked to Sai was very cool too ^^ and yamato seems to be an interesting character (i started to like him in first episode he appeared... his teleport move was badass)
