I agree, but this set in during the carbon freezing scene in Empire. 3PO suddenly becomes the voice that tells the idiots in the audience what’s going on and that trait follows him to Jedi.
It’s plot exposition. It has to go somewhere.
With respect, it’s bad plot exposition when it breaks the “show, don’t tell” rule of writing.
IMHO his exposition in ESB is forgivable as the audience is obviously completely unfamiliar with the potential outcomes of carbon freezing a human being. Having Threepio inform the audience is beneficial, and the way it was written was handled quite deftly.
Oh, they’ve encased him in carbonite. He should be quite well protected. If he survived the freezing process, that is.
Yes he comments directly on what’s happening on screen, but the primary comment is on the technical result of the process, with Han’s well-being a secondary thought. Exposition is delivered in an organic way with a dash of humour.
However in ROTJ it’s just amateur writing. The DarthRush edit trims this dialogue and the movie is better for it.
