What is the point of these? They sound horribly out of place, and I don't just mean that in a nostalgic "He shouldn't be messing with the old movies"
The new sounds don't integrate at all into the scenes, maybe Darth's second 'Nooo!', but his first was just... fake, and Obi Wans call is just weird, I mean, what was wrong with the first call he did?
As I've said before, somebody needs to give Lucas a proper project to do, to stop him ruining all his good films. Can't we think of some marginally good sci-fi piece that no one really cared for, that we could give him to redo?
