Very difficult to follow. Never answered why everyone on earth died. What happened to the settlement ship? Unrealistic scene where he is in freezing water and just gets out and goes on as normal.It doesn't works that way. He would have been dead in 15 minutes after being totally wet in sub zero temps. Love sci-fi movies, but this one was totally disappointing. Wasted time watching it when I could have been watching a Hallmark Christmas movie.
