I don't know what George's ability as a director has to do with audio. Probably a discussion for another website. I do agree he should have hired a director and should just be the producer. Irvin Kershner, the guy who directed Empire Strikes Back would have been the choice.
I'll bet SW-2 Clones will be a little flat also for this reason. George is a little rusty in the director department.
George is one of the major forces driving digital technology and HT forward; so we all owe him some thanks.
