For the most part I liked the ST dialogue, but unlike Monroville I really hated the "Do you know what's going on?" one. To me, it's EXACTLY what a PT battle droid would say in that moment.

These are soldiers so I wouldn't have them chattering, or sharing their thoughts in front of an officer just as a low rank soldier wouldn't do it IRL. Besides, they are merely bodyguards here escorting Leia, etc. Better keep them quiet.

The other one that doesn't work at all is the one blasting 3PO. At that point in the movie, the audience has absolutely no idea that the Empire is already there and in cahoots with Lando. We know Fett followed them, but not that Lando is about to betray them. That is a huge reveal when the doors open to show Vader. Hearing so clearly a Stormtrooper shooting 3PO would undermine the reveal greatly. I think that's why they specificaly went with a non-stormtrooper comlink voice for that one, and it works much better the way it is IMO.

Aslo agreed with them better not talking during the Han torture. But the one-word responses actually DO work quite well IMO like the one on the AT-AT or "stop that ship!" or when Luke is following them. :)
