Ok so I empathize for the original poster being flamed.
However, I do not find the original post to be very convincing. Yes, Minato could avoid genjutsu if he never looks at the enemy above the waist. But very simple Minato doesn't have the feats to say his chakra control was great enough to break genjutsu (considering Jiraiya was his teacher and he sucks at genjutsu), nor does he have the feats to fight with out looking at the enemy as a whole. He doesn't know about the one finger jutsu. We've never seen Minato attack someone when they blink so that may be out of character completely. Furthermore, Itachi as we know can perceive attacks and respond to them while his senses (they are all connected) are being overwhelmed. So I don't doubt that he can perceive an attack coming when he closes his eyes. He does have the sharigan to read Minato's movements. And as the poster above me noted Itachi can use genjutsu at long distances so making up distances doesn't reflect well in your behalf.
And lastly Eye sight and Movement are both tied to the mind. If you are controlling either of them you are controlling at least a part of the mind. Also bearing in mind the way in which genjutsu works, chakra is being delivered to your brain to deliver this genjutsu and the way to break it to stop your own chakra flow to your brain or to have someone else insert theirs. If vision is altered you could run directly into enemies blade without knowing it. If movement is impossible you are a sitting duck with or without ftg. But good try.
