Okay, that are some parts going down-hill. But c'mon, there ARE ups as well! At least I think so. Like the fight with the Shinobi Commando unit Vs Deidara, Sasori and Sai's ANBU brother. That was definetly an up for me.
It was an up for you? It was a boring fight. Neither Sasori nor Deidara did anything noteworthy. Sai suddenly became faster and blitzed the Akatsuki pair who was hovering dozens of meters in the sky, looking at him. Kankuro claiming that he's surpassed Sasori based on absolutely nothing.
