I'm not really talking about the Sharingan, but his skill as a ninja in general. We've seen him "dodge" several attacks in a much quick amount of time. The attack that hit him wasn't impressive looking, and yet it landed. Why? Not because Sasuke's lack of ability, but Kishi trying to show that he's not unstoppable. If the move was more impressive in some way shape or form, I'd accept it. But it just seemed so forced...
