Vader scenes are a must imo.
not really, I despise the ending with Vader. It’s shoehorning in pure fan service and takes away the flow from the sacrifice of Andor and Jyn at the beach. Having Vader only appear in Episode 4 would be way more impactful. As Vader’s slaughtering style in the hallway is way too jarring compared to his style in EP4. Focus should be on Andor with Jyn kind of a side character.
