Nothing. That is what I felt while I was watching this episode. I guess since the filler episodes have let me down since they started, I am anxioulsy starved for a REALLY good episode. I mean I think back to the sasuke chase arc, every single episode of the chuunin exam or even the Zabuza arc and try to compare.
Don't expect anything like that from the fillers. I can't recall ever seeing a filler that I thought was even remotely worth 20 minutes of my time.
