All the Female characters are lacking in development in the series - if you think about it - Tsunade and Hinata are the only ones that we have anything resembling a background on.

Tenten, Sakura, Ino, Temari - all are almost completely undeveloped in the manga.

I agree that Hinata would make sense as a medical nin - and I would like to see that happen. But if Sakura is going to remain a main character (and she barely qualifys as one now) then she needs to get off her ass and develop herself some.

The wierd part is trying to figure out how much time has passed during the "chase" story line.

Lee went from not having had his operation - to it being at least 2 days afterwards, plus the time it took for him to catch up (which seems to be about 1/2 a day) - so somehow 3-4 days seem to have passed during this messed up drawn out car wreck of a storyline. In that time hopefully the Kunoichi have been up to something?
