Just occurred to me that the whole Yamato/Sai idea just never worked out. The mangaka spent so much time on it too. Those two never did anything very useful or cool in the end and now look like it was a waste of time developing these characters. What are some other Naruto story bungles? Ideas that looked good in the beginning but never got anywhere? I can think of another one right now, but it might prove to be wrong in light of the newest battle with 8 tail. Basically, Sasuke's team building looks like a bungled attempt too. There was this whole segment of Sasuke running around recruiting them, and now none of these guys did anything useful.
