Setting aside the outright arrogance inherent in that statement... I don't recall the original trilogy EVER being marketed as an unfinished work... not when they were first released, not when they were released on VHS, not even when they were re-released the THX-certified home videos. Lucas has made BILLIONS off a product he now claims he never felt was finished, in his eyes. Nice of him to tell us AFTER we shelled out our money for it.
What's the statue of limitations on false advertising? Any lawyers out there willing to open up a class action lawsuit? I know where you can find a list of clients. ;-)
