I didn't think it was that bad, but by the end I was pretty uncomfortable with the moral message it was sending. I can't say more without spoiling, so don't click on the blurred out stuff below if you're hoping to watch it.
The message seemed to be that while forcing someone else to spend the rest of their life sharing your trapped existence in space would be A Bad Thing, it's probably OK because when they realise you're a nice person really they'll come round to the idea. No they won't. You'll still have stolen their life.
