@Jason

So you're saying Itachi only remained under it's effects because he wanted to? That isn't canon.

"Kotoamatsukami All-Ranges

The eye dominates consciousness changing what's in it's field of view into a puppet.

Uchiha Shisui's Mangekyo Sharingan utilizes the strongest Genjutsu. It exerts influence over the opponent, manipulating ones actions without them being cognizant of it. Victory can be obtained without causing a fight, a marvelous jutsu. Edo Tensei's bindings were overwritten by it's potency. The Sharingan Danzo snatched away from Shisui was used to manipulate Mifune, in-order to secretly dominate the gokage conference.

Kotoamatsukami was activated during the Gokage Conference. It's progression was manipulated to the user's own benefit."

4th Databook. The only reason mifune broke free was the progression was manipulated by Danzo as he went along. As we seen in the case of Itachi, the user can implement a command instead of remotely controlling them. Again, it is said to be the most powerful Genjutsu. Yet, all someone has to do is say "Aye you're under Genjutsu" and you're free? No. Lol.
