well i just watched it i didn't like the new conversation. My reasons are that the line "this boy , young Skywalker" doesn't sound right (doesn't fit together naturaly) and Vader agains mentions that he's just a boy (repetition that isn't needed IMHO). But i really loved the addition of the Emperors theme and that extra bit where vader bows then rises his head really works. Love it. But i feel that the end music is a bit too dramatic. i am warming to the interruption though, but i really do want to go with the closest possible way of returning the conversation to its original lines
