let's balance the morality... (spoliers)
(contains mild spoilers if you haven't watched this yet)
First, middle, and last: they were ALL DEAD. ALL 5000 plus crew would have died in their sleep pods after the damage was done to the ship.
They were ALL SAVED by the TEAMWORK of Aurora and Jim.
Now, I say BALANCE the morality, because, yes, Jim made a very bad decision. That's what the people in movies do: make bad decisions to give us some conflict in a story.
True. Done. But the BALANCE is that they saved 5000+ lives
The ship was hit, breaking down, and would have exploded and failed if not for Jim and Aurora working together to fix the issue. Not gonna say he did the right thing waking her, but it ENDED UP being a decision that saved the day.
And another lost plot point is that Aurora, apparently from the comments her friend makes on the video message, has never found anyone that was a good match to allow her to fall in love with. I mean NO ONE. Her friend is HOPING she'll find someone out there to fall for. And she did. The guy that took her planned life and ended up making it more than she ever dreamed of.
Again, not saying what he did was RIGHT, but in the end, it balanced out VERY admirably.
