You know, I actually liked Sasuke in part 1. Never was his biggest fan, but he complemented Naruto quite well. Naruto being the silly powerhouse, Sasuke being the technique-specialist. Both had strengths and weaknesses.
In part 2, however, Sasuke has EVERYTHING. While Naruto was a bitch for most part of the story, then had one great fight, then became a bitch, again.
Sometimes I wonder if Kishimoto knows how unlikable he made "his" Sasuke. But then I fear for the day Sasuke becomes Hokage, so I stop thinking about it...
