As far as George Lucas saying that Empire is his least favorite. Since when does any one believe what Lucas says anymore? People are always complaining about Lucas contradicting himself. You cant have it both ways. either what he says is admissable or its not.
Interesting point, but
1) You can't just say "people" are saying this about Lucas in attempt to rebut a specific poster, unless that poster has made the same argument that "people" have, and
2) I've never seen another quote by Lucas saying he loved Empire, therefore, in this instance, it seems Lucas has been consistent on that issue.
