Questions

Rating: 7/10 (3 October 2015)

I have a few unresolved questions about this movie:
First, wouldn't he have lost a lot of bone density and strength given the fact that he's on a planet with a high gravitational pull and has lost a noticeable amount of weight from having to ration his food supply?
Also, my biggest concern: wouldn't he have gone clinically insane?? I mean, I get it. He has some contact with people through messaging and he talks to himself with the video, but the sheer fact of being the only living thing on an entire planet for a year and a half would be enough to drive any person insane, good sense of humor or not.
It was a great movie, don't get me wrong - kept me on the edge of my seat, holding my breath, all that, but those questions really stand out to me...
