No.

Another change has been made on the "Star Wars" Blu-rays. Originally in "Return of the Jedi", when the Emperor is attacking Luke with force lightening, Vader just stares quietly and then he decides to save his son and throws Sidious to his doom. But Lucas is changing that.

As you see above, Darth Vader now says "No" when deciding to save his son. I don't know why, but this actually bothers me. There's just something about him not saying a word that's just so right. I don't mind the changing of Yoda,but this bothers me and I don't know why. Perhaps this is how people felt when they changed Han shooting first. You know it was originally something else, but now it's different, it's not the same. But I guess I can get used to it. Good thing I have a copy of RotJ before this change. So I can watch it either way. I just hope this will be the last thing George Lucas does to the franchise. It's been changed enough.
