The "Nooooooooo!!" added to ROTJ isn't as bad as I had feared. Not nearly as bad as the one in Episode III anyway.
Having only ever watched ROTJ maybe 10 times in 25 years and mostly on small screen VHS I had never noticed that as Vader is lit up by the Emperor you can see his skull. I thought that was a new effect so I went back to the GOUT to check and saw it was there too, but as I watched the scene in the GOUT I *Almost* missed the "NOOOO!!" - it just seemed oddly quiet...
NOOOOOOOO!!! What is wrong with me?
I didn't try the other audio tracks on the Bluray, I suppose it is on all of them?
