I personally am fine with the “don’t choke” comment that one is ok. It’s blunt and true to Vader.

But a lot of his other lines he just is not written Blunt enough I feel.

Even Later on when he say’s “prepare a boarding party” if you compare that to the empire strikes back “prepare a boarding party” then it’s like chalk and cheese.

Probably age as DC put’s it

It just does not have enough urgency or omph in it. I don’t think I am alone in this feeling but it does not break the film at all. It just sounds like another Vader.

Speed of Delivery is possibly another factor. I would not be surprised if his voice was sped up when they did it in the original.
