I think most of the reason I don't like Sasuke is because I find the avenger plot a tad overdone, and I can't see why Sasuke is so impatient now (Naruto has Kyuubi. Sasuke doesn't. It's understandable); but on the other hand, I'm the sort who thinks the best revenge is living well and that it doesn't matter who kills your enemy as long as he is dead. Plus Sasuke intends to resurrect his clan, and this seems to not work towards furthering that.

Yeah, and I don't see why Tsunade sent the genin to do it. Seems misconceived, but of course they need to send someone, even if Sasuke left of his own free will, because he does have an advanced bloodline.
