I do feel there were a lot of scenes that could’ve been handled better, with the right pacing and music, Vader’s helmet’s reveal being one of them, which felt almost casually shown on the screen.
As somebody who avoided all trailers, and had never seen Vader’s melted helmet until it’s appearance in the film (and therefore wasn’t expecting it), I thought it was just right.
But that’s just my opinion.
Obviously everybody’s entitled to an opinion. It’s just when it starts getting into frame by frame ‘they should have done it like this’ that it gets a bit tiresome. If any one of us were in the hot seat instead of JJ, I’d bet good money on the finished film being a lot worse. Sure, it would contain zero logic flaws and adhere slavishly to Jedi lore, but it would probably be dull as dishwater, appeal to nobody but hardcore fans, and be a total mess from a storytelling point of view.
