The big confusion here I think comes from the fact that SW borrows from so much sci-fi that it does give the impression that it actually does make some scientific sense at times, but then all of a sudden there’s a space-slug with it’s own ‘gravitational pull’.
My objection to the space slug isn’t so much that it has its own gravity, as maybe the asteroid it lives on is large enough to have its own gravity, but that the slug is living in a vacuum. And worse, the characters step out of the MF into what they believe is a vacuum. That, I think, is a case of TESB breaking its own rules. If TIE pilots need life support space suits to survive space, so does Han Solo, when he leaves the safe confines of his ship.
However, I wouldn’t say that the space-slug scene is “stupid” because it works well within the narrative, as well as within it’s fantasy logic…So I’d argue that the space-slug is anything but stupid, I’d say it’s pretty brilliant.
I’m not so sure about that. I see your point, but I think the whole slug thing was unnecessary. Just sort of a 1950s “Flash Gordon” thing that Lucas was fond of.
