I liked the Leia scene and I read it as intended: Leia instinctually acted to save her life with the latent powers we know her to have. Maybe the moment was too contrived or the execution a little funny, but it worked for me.
It was a bit out of place, she probably would of died in the explosion and would of exploded in space but who cares it was a way they could keep her alive.
People don’t explode in a vacuum. That’s a movie cliché that has no basis in reality.

tl;dw: It is theorized that the human body can be subject to the vacuum of space for up to 3 minutes before the subject dies. The sticking point with the film is that the skin and organs should swell a lot. Not 1990’s Total Recall levels of swelling, but still a highly significant amount (like 2x normal size).
AFAIK, it was Outland (1981) that started this human water balloon nonsense. A pity as I like that movie.
Kubrick got it right in 2001
and even gasp Moonraker got it right!
