Have we ever seen him that pissed off onscreen before? Because I don’t think so. And I think that one short scene is Vader’s best in the series so far.
In the Tantive IV in ANH.
Also this is a younger, more passionate Vader. It’s an adaptation of himself in the 2017 comics by Charles Soule. Which is what I’ve always wanted. And I can’t wait to see more of him.
And he still focuses his anger appropriately, as he does in the later movies.
