Don't you think that, if Lucas wants these six movies to flow as a whole saga, Lucas should make it so that the viewer doesnt know that Anakin is Darth Vader until ESB? Like, we all know that he is Vader, but like generations from now that will watch it Ep. I to Ep. VI will not watch the movies with the preminition that Anakin turns into Vader. Then, the surprise in ESB will still be the biggest twist in movie history. In Ep. III, Lucas needs to make the audience believe that Anakin dies after his battle with Obi-Wan and then this new Sith appears because Tyranus is killed (by whoever, thats an entire different thread though). That new Sith is Darth Vader. Now, the audience of the future believes that Anakin was killed before he could turn evil and this new Sith has come to stand at Palpatines side. Then, in the second to last episode we find out that Anakin has not died but has been Darth Vader all along. Does anyone else agree with me?
