But what I really think needs to be done with Episode III is to leave the big cliffhanger of the movie and the Saga in general, is the fate whether or not Anakin dies. Meaning Anakin's presumed death after the lightsaber duel with Obi-Won should be a mystery...with this "new" character of Darth Vader opening up a new cliffhanger of who the hell he even is. Simply not possible. Too much dialogue in the originals gives it away to a prequels viewer. For example: "A young Jedi named Darth Vader, who was a pupil of mine until he turned to evil." "A tremor in the Force. The last time I felt it, was in the presence of my old master. "If once you start down the Dark Path, forever will it dominate your destiny, consume you it will, as it did Obi-Wan's apprentice." All these lines tell us that Vader was once Obi-Wan's apprentice. In the prequels, we see Obi-Wan training an apprentice. His name is Anakin Skywalker. Secondly, have you ever heard the expression having you cake and eating it too? ESB was a surprise because no backstory information was given, there was no prequel trilogy. The prequels will give us that backstory. You can't expect the experience of watching the originals to stay the same when you change the order in which you watch them. The only way to preserve the surprise is to not watch the prequels first. If you start with the prequels, Vader's identity will be known.
