The whole reworking of that final act of ESB to accommodate Vader arriving on his shuttle does really slow the pace down.
That’s really the crucial thing. It completely ****s up the pace, which is something that George Lucas and his post-97 team obviously have no clue on, seeing what they did to the first act on Tatooine in Star Wars.
You have this gorgeous and frantic climax going on, and then the movie just stops dead in its ****ing tracks so some CGI guys can play in their sandbox. Give me a ****ing break.
