Quite frankly, I don't think George Lucas was thinking half the things this guy says he was. This comment on the article also sums up a valid argument:
"There is absolutely no element or character in the original trilogy that isn't delineated in stark black and white terms"
Interesting. Han Solo is a smuggling criminal whom acts as a gun for hire. Lando is a degenerate gambler responsible for our hero's capture. Darth frickin Vader- the supposed epitome of evil in the first two films- KILLS the emporer- the real epitome of evil- in the third. Perhaps I am obtuse, but I do not find those terms to be starkly delineated in black and white.
