Wow, I'm a bit surprised that you've gone back on your desire to have the Yoda scene in the movie. And the fuel scene thing would make the already too long opening sequence even longer. Plus, the whole premise of them swimming around the fuel tank of the ship just seems so... silly. And I agree that there had to be scenes showing that there was a war going on, but I just didn't happen to like any of them. It bored me so much that I didn't even notice the Wookiees the first time I saw the movie. But it's obvious the real reason it's there is not to show a war going on, but to show off Chewbacca. And the Obi-Wan/Grievous chase was horrible, simply because Grievous was such a crappy character, and that stupid shrieking furry lizard certainly didn't help me enjoy it any more, especially when I realized, "Oh, wait. They put that same sound in the 2004 DVDs. Now I see what they were doing."
