Alright, as we all know Sasuke was a overly emo, try hard, bland personality cliche character before he left, however it seems that he has gain a lot of qualities that are unexpected under Oro's tutelage...
Maybe "likeable" was to strong of a word, but he seems to be a competent leader, and actually likes and cares for his teammates. He also appears to be a lot more...relaxed I suppose you could say, and no longer dark, simply driven. All in all he appears to be relatively "normal".
Considering the conditions of his leaving Konoha, and his personality at the time, add in who he has been living with and I was expecting Itachi 2.0, the Pouty version! But totally out of left field I find myself actually despising him less, and becoming curious about where he's going to go and what his plans are, specifics, not just "lolz kill itachi".
Am I alone in this, or have you all seen a positive change in the character as well?
