I think that there are a third of the list of parallels are legit. Things like romantic dialogue are a necessary part of the story if you have two people who are in love. It doesn't mean Lucas is re-doing it. Other things like Obi-wan's actions on Geonosis and Mustafar are legitamate parallels. I think that Lucas is liking concept that he felt worked in one movie and plugging them into another. He has been reusing ideas from the beginning. A New Hope originally had Luke checking out the Star Destroyer battle from the surface of Tatooine. This of course was cut, but Lucas brought the scene back for the beginning of Empire with the probe droid. If you want to talk about re-using and remaking ideas, Jedi is much more of a re-make of A New Hope than Revenge is a remake of Clones.
