If a few years have elapsed between ANH and TESB why is the Emperor just now realizing that "We have a new enemy." This 'revelation' should have occurred immediately after the Death Star was turned into smoldering space dust. It would seem that the Emperor had an epiphany, or a vision, that permitted him to know the identity of that "rebel who destroyed the Death Star." In this there is some reason to accept the new dialog since it helps clarify the nature of this conversation and the nature of the Emperor's visions. I don't think the old dialog is any better than the new, and I don't quite understand the arguments that "it adds nothing to the story", etc, in fact it clarifies for the audience the nature of the relationship between the Emperor and Vader as well as establishing a link between the events of ANH and TESB. I do agree that Ian isn't giving us a stellar performance, and has slinked back to the lazy dialog of the ROTS. I love the visual corrections Adywan has done on the overexposed face of the Emperor from the 2004 DVDs, but I liked the new dialog and as far as storytelling goes it does accomplish subtle plot points which are absent in the old dialog. The fact that Vader seems to be hiding his search for Skywalker from the Emperor, "How is that possible?" and the Emperor's seeming unaware, "Search your feelings." I doubt these few lines of argument will assuage those who believe TESB is by and large without fault, but I thought it wouldn't hurt to throw in my two cents.
