Hey the character had potential when he had been introduced, but Kishimoto unforunately didn't strike a desire to ake him more than he is. He did say he created him at the last moment but that doesn't excuse his lack of progression of Sasuke to a simplistic role.
Jibajab said: Sasuke is a badass, it's just that Kishimoto can't write him good enough to prove it.
THIS. Then again, Kishimoto can't write a decent female character to save his ass either. I think he just can't write PERIOD and is coasting on art alone...and it's working.
