It's just scenes where there's a lot of dialog.
eg...Between Tarkin and Leia...I think you can really tell what's been dubbed and what was spoken on set. All original stuff, but it just stands out a mile now. Just seems to be a lot of hissing in the background.
I'll have to watch it again...t'was very stoned...day off work an all!!
Empire and Jedi are fine......Just ANH seems to suffer the most.
But the new Fett voice...now, man, that's a shame.
Big mistake!!
Oh and when the Stormtrooper bangs his head there's a "boink" sound now too!!
Oh dear oh dear!!
