Because of the complexity of its pronouns, the Vietnamese translation adds an extra layer of depth to the otherwise shallow dialogue of the Star Wars original trilogy, which I watched on TV in Vietnam.
People speak to droids with the pronouns used to speak to pets or farm animals. Droids address people as professional superiors.
Droids speak to each other like they are siblings.
Vader speaks to everyone (except the emperor and Tarkin) as an arrogant superior addressing an underling.
