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?

As I said in my review, I do think it makes Vader a bit weaker, considering Tarkin's tone when he says "this had better work." It comes off as an "...or else" type of message to Vader, at least to me.

But I do feel this is much more debatable than "terminate her, immediately!" so if it is kept as-is, I think it could still work.
