George Lucas has once again earned the wrath of his fans.  Six of the films are to be re-released on Blu-Ray September 16, and Lucasfilms has confirmed that several changes have been made.  Among these changes - some of which are positive (such as returning lightsaber colors back to their original colors) are the following, which have enraged fans:

- The puppet used for Yoda has been replaced with a CGI model in "The Phantom Menace".

- Obi-Wan's Krayt dragon call will sound different.

- The Ewok known as Wicket in Return of the Jedi will now blink, via CGI.

- Darth Vader will now scream "Noooooo" as he picks up the Emperor and throws him to his death, to save Luke.

I am not a particularly rabid fan of Star Wars, myself.  However, I can understand why die-hard fans are upset, especially in the case of the Darth Vader scene., which was perfect as it was, in my opinion.  He didn't need to say a word - the silence actually added to the emotional impact of the scene.  His inner struggle was more poignant because of the silence; the turning of his head from one to the other before he took action was evidence of his turning away from the dark side and embracing the Force.  However, while I think this change, and many of the others, are unnecessary or even stupid, I don't see why they are that worth getting upset. The original films are still there to be viewed in their original form for those who prefer to see them and remember them that way.

How do you feel about these changes, or about any of the changes made in earlier versions?  Which changes do you think were made for the better or worse?
