Seriously, think about it: Lucas must have some reason for adding the NOOO!,

This is only a matter of ego...just as the surgeons who refuse to acknowledge when they make mistakes.

There are two ways to act when we are wrong :

1 - accept it and make the change

2 - refuse it and continue along the same path (to convince itself and try to convince the others)

Lucas has seen all the bad reviews about the "nooo !!" in ROTS...and instead of recognizing that it was a very bad idea and badly done, he persists and signs.

How can he hope that this new "nooo!!!" in ROTJ will be well received !!!?

We are humans, and humans make mistakes ... Lucas is no exception...I just hope that one day he will accept it.

and it's not a matter of vision here...different vision or something...it's a matter of taste : good or bad...this new "nooo!!!" is just wrong in every way, it is an offense to good taste.
