when i saw the scene my first thought was “how the heck is she alive?”
People have survived being exposed to the vacuum of space before. Also remember that she is surrounded by the air that got blown out of the ship, which she could have subconsciously kept around her using the Force.
IMO the ‘Space Leia’ scene is problematic, because it is heavily switching between movie genres and their specific rules. The overall genre of the STAR WARS movies is science-fantasy. But the movie event of being sucked into space belongs mainly to the science-fiction genre. Being sucked into space is very well ‘documented’ in lots of sci-fi movies and even the dumbest movie-goer knows what happens to a character/person by that event. The rules are clear. But Rian Johnson tries to solve that science-fiction problem with the rules of the science-fantasy genre, let’s say magic, namely the Force. And that is why the scene does not work.
