Yeah Kakuzu's wasn't the greatest. I didn't have problems with him losing to Naruto as much as the way he did it. Kishi was obviously trying to display Naruto's strategic abilities but a regular clone feint like that is not something the audience is new to nor was it his best one to date. Apparently Kishi said that he had to rush that arc to showcase Sasuke.
She honestly won the fight in my eyes. She prepared for Uchiha nonsense, and got trolled by more Uchiha nonsense. We didn't even get to see her boobs :'(
On a side note... All the other akatsuki members ripped off their cloaks and fought, why not Konan? WHY!?
