Uchiha Sasuke and Uchiha Itachi dorknerdface!
Itachi really got the short end of the stick story wise though, really wasted plot lines. (I guess they saw it too, why he's getting his own spinoff next month lol) And how odd Kakashi copied Mangkyou with one eye after seeing it once and Sasuke's two eyed butt got mangkyoued twice and never copied a thing.
Especially after the mangaka took the care to highlight both their jutsu copying prowess prior.
Kakashi is "the Copy Ninja", so that's prolly why (still lame, I know)
I feel like the current plot of the anime (newest non-filler episodes) don't really fit that well into the show as a whole...
I'm basically only watching the anime at this point for the action scenes and have given up on the story a long time ago (after that Jiraiya/Pain BS)
