Sorry....late to the party here. Just saw this last night. I will say at the outset that I mostly enjoyed the movie. The millenials sitting behind me, did not, judging by their post-film reactions. "NOTHING happened. I thought some aliens might show up or something!" Apparently they were looking for a science fantasy film and not a science fiction film
Anyway, regarding the moral dilemma as depicted in the film, I thought it was handled OK in the movie. Not well, mind you, but OK. In a machiavellian sense, the whole moral dilemma was effectively diffused in the third act as Jim would not have been able to save the ship without Aurora's help, since it took 2 people to vent the reactor. So if he hadn't woke her, everyone would have been dead at the end of the day.
Laurence Fishburne was a bit of deus ex machina, but he did serve more than one purpose. One was to give context to Aurora on Jim's moral dilemma, and the other was to enable them to have access to more areas of the ship and open up further possibilities of living and survival into the future. I recognized it at the time as being kinda convenient, but I didn't have a huge problem with it.
I did have some superficial beefs with the film that have more to do with the laws of physics and inconsistent story logic:
1) I don't know why Aurora was drowning in the pool water. Sure there would be no buoyancy in zero gravity, but there would be something to resist against that would allow Aurora to push the water away. Also, in zero-g, I would suspect that the more dense water would be easier to push into the less dense air and that it would not have stayed globbed together so much.
2) I have my doubts that Jim's flinging of the door (which had much less mass than he did) would have reversed his direction when he was outside the ship. Slowed it maybe a little, but not reversed it. Also would have liked to have seen some stabilizing jet streams at the extremities of those suits as nobody spun out of control too much as I would have expected. Maybe he didn't think of it, but why not wrap your tether around the pressure release door handle and then retreat to a safe distance and then give it a tug? Problem solved.
3) When fixing the reactor computer, Jim plugs in another computer module because "there are redundant parts for everything", yet there is only one "Auto-Doc" medical bay??? It seems to me that the medical triage and treatment module is one of those "Class 1 importance" type systems that there would surely be a redundant pod in storage somewhere.
All in all I'd give Passengers a generous 3.0 / 4.0.
