I'd say Whedon. The other people on the list (that I know of ) don't seem like good fits, especially Abrams. He's already destroyed my favorite sci Fi franchise. If they let him near SW, I'll probably go insane.
Nah, he'd probably just make it good again, like he did with Trek.
While I'd like an Abrams SW, I like him where he is now.
Id say either Matt Reeves or Brad Bird would be two guys I could see doing it, in my head, and in reality.
If we were just going wish list though, I'd LOVE to see a David Fincher SW film.
