Where were all these positive feedbacks 2 years ago when I first posted the clip... :)
Ok, given the positive comments, I will use this solution (Tarkin remains silent), and make the final tweaks to finalize the scene.
This leaves just the following scene: Tarkin says: "I'm taking an awful risk, Vader. This had better work."
But whether this makes Vader weaker, or just Tarin insecure is not so clear. Any ideas, opinions?
