Can you share some links to substantiate these claims that lucas didn't have a clue as to what he was doing, and moreover hadn't been infuenced by Campbell? Because I've paid quite a lot of attention to both of them, and thats completely contrary to what I've understood. Moreover, the OP link and it's follow-on say otherwise.
