After having read the first page I got very excited about this project. I myself have been working to do the same thing. I really am not too big of a fan of the prequels, but I still enjoy them and the thing that bothered me was that they are impossible to watch in order. So I decided to start working on my own edit to smooth out the rough parts. So far I have only finished a rough cut of Menace. Concerning Obi-Wan telling Luke the truth. Having watch the OT countless times, I never really saw Obi-Wan's lying to Luke as harming Obi-Wan's honor or anything of that sort. I don't think a lot of people did. What has changed? Just because now we have seen Obi-Wan leave Anakin alone on the shore of a lake of lava to burn to death? I am sure in Episode III Obi would not have just left him there if he thought he would be rescued. I would have liked it better if in Ep 3 Obi thought he was dead, not left him for dead. Then be surprised when he realized Darth was his old padawan. But at any rate, let us look at it from this point of view. We have said Luke's NOOOOO! in Empire was a bit of over acting, and that now the surprise is dead so the scene has no reason to live. Well, just imagine you believe your father was a great man, but is now dead. You don't know much at all about your dad or mom, you aunt and uncle always seem a bit sensitive to that subject and tell you as little as they can. One day you meet an old man who it turns out fought in a war with your father. You realize either this man is lying to you or your uncle and aunt have lied to you your entire life. Then he says that your father was his good friend but he turned evil. And he is not in fact dead but he is still alive and is Saddam Hussein. Don't you think you would be doing more than merely going, "whoa" inside you head as Luke appears to be doing and continue reconnecting your droid's arm. Comon, these things are contrary to everything you have ever known your entire life, maybe you had some idea that your uncle wasn't quite telling you everything. It is clear that Obi-Wan was trying to protect Luke. Also you can see from Episode III that the whole thing was prettty rough on Obi-Wan emotionaly. He has had plenty of years living alone in the dessert to reflect on the tragic turning of the man who was like a brother to him. You don't even need the line of Yoda telling Obi not to let the children know of their true parentage. It just isn't needed. Probably Obi-Wan has consoled himself through the years saying that Anakin died the moment he turned to the dark side. It isn't that Obi is merely lying through his teeth. Also at this point Obi-Wan believes that Luke is still unkown to Vader.
Anyway, for my personal edit of the saga, I intended to have a silent flash back of Obi-Wan yelling "Anakin, you were my brother!" and Anakin yelling out "I hate you!" when Obi-Wan is telling luke about his father being murdered by Vader. I think seeing that the old man is remembering this that was probably the most painful moment in his life when the man he considered his brother was lying on the ground burning to death and using all his force to shout the words I hate you to him. I think this shows the pain old Ben still feels inside and makes his lying more justifiable.
