I think you meant Kazekage. Anyway, i liked the Gaara development also.So please why do you have to complain about Garra finally confronting his own demons and come to terms with his past and take the position of hokage. I'm happy for Garra. I"m honestly disappointed that he lost to the mouth guy but I guess it had t o happen for the story to progress.
I also had no doubt that Gaara would loose the fight, but i thought maybe in a different way, with the other Akatsuki member getting invovled, it seems the Akatsuki are going to be around for a while, also meaning that Naruto and Sasuke aren't at the level or a little underneath maybe to take on an Akatsuki member. It would be good to see how they would fair though.
Gaara may have put up more of a fight if he wasn't protecting the village, but would have lost in the end.
