Hated it since day one. Sasuke goes from using wire, multitude of jutsu and tactics to smashing down doors with giant Susanoo fists to solve his every problem. Boo.
I mean why not? Chakra itself is powerful so someone came up with the idea to make it into human form. Madara can spam it w/ clones and defeat the gokage so yeah its probably the most haxxed techs of the series.
