The visual is Vader acting calmly and deliberately. Yelling, even through the mask, doesn't go with that.
i don't see how his verbal expressions are that different from his actions. the first "no" is downright dismissive. the second "nooo" is a lil angrier and confrontational, sure, but the man has put in a good 20 years to dark side type work, punching the clock at the death star. i think his instant rebellion warranted the action, which is deliberate, but understandably (and i thought obviously) not all that calm.
Furthermore, the Emperor is zapping away at Luke and not paying attention to Darth. Part of the reason he isn't paying attention to Vader is because Darth isn't screaming 'nooooooo' during the scene.
he's not paying attention to darth because the emperor is a shit. the man shoots lightning bolts from his hands, and never once even thinks to wiggle as vader picks him up and brings him over to the freshman trashcan. yeah, he's seemingly unaware of the "nooo" this time around, but in the originals, he wasn't even aware he stopped facing luke!
Once ESB came out, we all knew those prequels would be about Luke's dad being Darth Vader.
you knew there were going to be four more movies ...in 1980? shit, i thought most people didn't know it was a nine issue series until the internet. fuck, i didn't know what a "prequel" was until ... well, the prequels came out.
If anything, the bigger surprise was that Lucas (a) waited so long to do any films after Return; (b) didn't do sequels first and then prequels.
i still don't understand why it was more important to tell 1-3 instead of 7-9. maybe you
were aware there was an earlier story to tell, but i think most casual fans had no idea, and the "logical" step would have been advancing forward.
even with the 20 year difference, i think it woulda been pretty sweet to have an older luke / han / leia, etc, all featuring the original cast. that, to me, was the biggest loss of the prequels (immediately followed by their terrible, terrible, terrible acting), that the characters star wars fans grew up loving weren't featured in the new stories.
