Other mistake: The Kepler's energy core is a huge nuclear reactor. It can easily obliterate the whole station so its accessibility should be protected by all kinds of fail-safe systems and high level security protocols, yet, Norah - a simple mechanic - can fire it up and overcharge it without any password, keycard, identification method or such, only by pressing a few buttons, then 'space' (not even 'enter'). There is not even a confirmation process before switching the reactor to terminal overload.
Other mistake: *Spoiler Alert* The strength of the underwater suits is wildly inconsistent. Rodrigo's suit almost immediately cracks and implodes, killing him. Paul's suit is easily ripped open by the creatures, also killing him, but Norah is repeatedly slammed into the sea floor by one of the creatures and her suit remains remarkably intact.
Suggested correction: It is stated by one of the survivors that one of the helmets was damaged. Rodrigo had the damaged one.
Actually, that's not completely accurate. She says something like "Faulty, I knew they were faulty." That also doesn't account for the fact that the creatures tore Paul right out of his suit, but couldn't seem to do the same with Norah.
His suit was faulty. He noticed a crack when he first picked it to put it on.
Other mistake: The station's escape pods are not too big but surely big enough for 2 slim woman - a possible weight limitation is out of question as well. They could easily use it together and survive, so Norah's self-sacrifice makes no sense at all. Besides, what if all 6 crew members make it to the pod hub? Rock, paper, scissors?
