Science is a very humbling subject in society. It's something that a majority of people around the world love to study, and yet there are a lot of parts of it that have to do with us understanding our own mortality. Add that to science fiction films, where, yes, the word fiction is a part of it, but there is a lot drawn from reality implemented into the story. If the genre does anything well, besides maybe giant monsters at times, it makes us question our existence and the dreadful end to all of whatever this is.
