Hmm, just watched it. I must say I think the Anakin vs. Obi-Wan battle is worse rather than improved in your version. My biggest annoyance with that scene has always been how Obi just leaves his "good friend" to die burning to death. I think it would have been much better played if he would have fallen off a cliff or fallen into the acid/lava and disappeared. In your cut Obi-Wan does not only leave his buddy while he is burning to death and it is a pretty sure thing he will be dead momentarily, but instead actually leaves him lying there on the bank limbless but otherwise healthy to pull him self to safety with his remaining arm. Also whilethe dialogue between the two isn't the best, I think it is pretty essential that Obi-Wan sees his friend has truly turned and that there is no way to get him back. In your version it is more of a "okay Anakin, I see you have choosen to become a Sith, so I am going to murder you now". SOme of the dialogue should go, but like Erik said, some things like "You've done that yourself" don't sound bad and I think are pretty essential to the emotion of the scene. Otherwise you just have two guys trying to kill each other. I completely agree with the removal of "If your not with me then you're against me".

Also I also find the abrupt ending an extremely terrible choice (not trying to diss, just trying to give constructive crit.) I think you and I have similiar goals for the ending. Have you seen my clip? I posted it in the Starkiller Ranch thread before. You can dl it here. Keep in mind this wasn't made to showcase my editing skills, but was rush together in a matter of five or ten minutes. I too have tried to preserve the Darth Vader secret, though I know inevitable people will figure it out before they reach the ending of ESB, I still think it is fun to preserve and not to have completely in the open. I have also tried to preserve the Leia thing by only showing the birth of Luke. Check out my clip and see what you think, if you like any of my ideas feel free to use them or modify them and make them your own.
