Here.

For the most part its just a few minor cosmetic changes that I don't mind too much. But the one that completely fucks over the new Blu-ray release is the addition of Vader saying "no... NO!" during the climatic scene with the emperor. The scene has now lost pretty much all of its impact.

In the original scene at the point where the emperor decides to kill Luke, the focus regularly switches to Vader's reaction to Luke's intense suffering and pleading for help. An audience that does not know the eventual outcome of the scene is left in no doubt that its Vader we're meant to be focusing on. Everything about the scene is designed to build up audience tension and give them minor hints that Vader may be having a crisis of conscience. From the way Vader's focus changes from Luke the the Emperor and back, to the way the music builds as he does so. But not enough is given away the audience is outright told what they should be thinking. The end result is that a scene of high emotional tension leads the audience to a place where they're meant to be taken by surprise at Vader's final actions and the way the music changes completely after the clever use of a single bass drum percussion beat lets us now that.

All of the drama and surprise has now been shit on from a great height by the badly placed overdub of Vader telegraphing his eventual actions to the audience. The single percussion beat that John Williams put in now cannot be heard...

If I can say one positive thing about this it would be that I can thank Lucas for saving me money by informing me that I shouldn't buy the new Blu-ray release. :/
