I recently watched Star Wars again, and noticed something new about it. The robots are like slaves.
At one point Luke removes a “restraining bolt” from R2D2, which seems to be designed to stop him running away. In other words, at least some of the robots want to be free, and will run away unless they’re physically prevented from so doing. The human characters, including the ‘good guys’, know this and have no problem with it.
Also, R2D2 doesn’t get a medal, despite also risking his life (and yes, he does have a life. Everyone in Star Wars treats droids as being alive).
This seems like a very…strange plot element, to say the least. It doesn’t seem to fit with movie serials, Westerns or the film’s other influences.
More ‘serious’ science fiction might deal with this issue – but that’s the point, it would deal with it, not just have it without any comment being made, either by characters or film-maker.
