The whole reworking of that final act of ESB to accommodate Vader arriving on his shuttle does really slow the pace down. Bad enough that the perfectly placed and spoken ‘Bring my shuttle’, which I think most agree really highlights Vader’s anger in that moment and more than enough to explain how he arrived to his Star Destoyer in short movie time, is gone but in the midst of our heroes making their escape is all this cluttered stuff showing Vader leaving Bespin and arriving in the docking bay. Really not necessary. Sad thing about the Special Edition changes is they can go three ways. Either you fully understand the change and feel it was justified, you’re slightly confused by it but sorta get what they were doing, or you can tell George did the change just to do it. I think this one falls somewhere between the last two with it reaching pretty close to the third.
