Quoted from kwiKimart:Onto the Darth Vader NOOOO issue, it seems silly at first, but I feel like Lucas should've made Vader go for more of an aggressive NOOOO, but with James Earl Jones, it came out more comical than serious.
Comical is being nice.
Given all the other CGI "enhancements" (like R2D2's stupid rocket legs) in the prequels, I fully expected a pair of miniature windshield wipers to extend across Vader's helmet lenses and wipe away crocodile tears....
That one scene turned the most iconic badass in movie history into a total pansy. Epic Fail.
