I liked old Lucas the one who said "a special effect without a story is a pretty boring thing"
He articulates this point far better in the peecher book on the making of jedi, even taking an anti cgi stance.
Funny how modern Lucas made sure that documentary is not on the blu ray,lol.
For those who are not following i was referencing from star wars to jedi, which along with the OOT is now buried.
