Why was everyone Amazed at Sasuke putting the Bijuu in Genjutsu?

[King Of Pop]

Hagoromo pretty much said he saw them all, so no.

no he said he merely took a glance, big difference. some bijjus were at his back and some at his side and they were caught

Because all Nine Beasts weren't in the same area as they were. If they were, Madara/Obito would of controlled all of them and put them in a summoning contract.[SUB] You must be registered for see images [/SUB]

You fail to comprehend the scale of this feat.

Sasuke did it with a SINGLE glance. I don't doubt that Madara and Obito could control all 9 with Genjutsu but they would have to look at each one individually, which would take longer. Sasuke did it simultaneous. That's what makes this Genjutsu feat so big. Because he did it with such accuracy and speed that has been unseen in the manga up until this point specifically.

Not really but whatever floats your boat.

"not really"? Hagoromo makes a statement that he saw them all, but you say Sasuke didn't "really" see them?
