It was a TERRIBLE movie. Completely unrealistic.....Spoiler Alert....... A massive spaceship being clobbered by hundreds of pieces of ice, not once but twice, and then repaired by 3 people in one space walk. Urgently waiting till it is safe to enter an airlock to save someone's life and then spending more than 30 seconds watching her blood floating in the airlock without helping her. And the last one is not even clear it happened (never clearly explained). Falling in water at extreme sub zero temperatures and suddenly being dry and surviving fine for another day in sub-zero temperatures.
