Actually Lucas did the same political message with his first three, but managed to make the Jedi so deadly dull in the process that Darth Vader was actually the most interesting (and often secretly admired) charactor in the first three movies.
I agree with you about Darth Vader. The Empire Strikes Back was far and away the best of the series so far. As for the review, just for the record I posted it for discussions purposes. I don't know if it is anti-Bush or anti-anything for that matter because I haven't seen it (obviously).
Why be secret about it?
Yet another Hollywood/Communist movie that I will skip. They just can't wait to tear down America and God, every chance they get. No big loss.
