To be fair, lack of Hollywood gloss was one of the reasons why I enjoyed it so much, I thought it was classy and stylish I liked the characters, the cinematography, the plot and the topics they examined, especially all the stuff about artificial intelligence, human nature, the future (and the past) of humanity. Quite a few interesting ideas there, such as the origins of life on Mars and Earth, didn't expect that! For me, that's proper science fiction, very refreshing...
