I can almost see wanting to rid himself of the whole responsibility. It's sorta like what Shatner said on SNL 20 years ago:
"Get a life people. You've taken something I did on a lark and turned it into some sort of gigantic waste of time..." (or something like that).
But seriously. He added some scenes with better FX, and even if he DIDN'T make Greedo shoot first people would have been freaking out. I PREFER the newer ones with the improved FX. If I have to have Greedo shooting first to get FX that are awesome, so be it. Anyway, people act like the universe ISN'T HIS TO DO WITH AS HE PLEASES. Now it's someone else's responsibility. I bet he's saying GOOD RIDDANCE.
