I don't really like him but I don't mind him.
I don't like the fact that he's in love with Sakura, but I guess you can't choose who you love.
I think he's annoyingly stubborn, repeatedly trying to save Sasuke. I mean even if he does, and Sasuke comes back to the villiage, what shall the villiagers think of him? Are they meant to ignore the fact that he plotted to destroy Konoha, and the fact that he is a rogue ninja?
I also don't like the way he acts all tough and shit, it annoys me, like he learns how to do the rasenshuriken, and then acts as if it is a Shinra Tensei or some beast shit like that.
