I don't explicitely remember feeling too much about it. I do remember one part of the movie giving me a question to think about, and that was the burned man on the second ship.
The first ship had a crewmate who was exposing himself to more and more sunlight as well, getting small burns, and I think, he was starting to seem pretty sketchy the more he exposed himself. Then he ended up dying though.
Sort of left me with the question, of whether or not that burning by exposure deal was a natural phenomenon.
I dunno. Strange movie, of the bits I remember.
