Of course, no discussion of 2015 science fiction movies would be complete without mention of this year's modest little endeavor from Disney/Lucasarts:
"Star Wars: The Force Awakens."
On the meta level, the film doesn't have much direct conjecture on contemporary technology -- everything happened a long time ago, after all, in a galaxy far, far away. Plus, "Star Wars" has always been more about space fantasy than hard sci-fi, anyway.
But those interested in the "soft sciences" of sociology and anthropology will find plenty to chew on. The movie is basically a masterclass on how mythology works -- how we tell ourselves the same story, over and over, in different times and places. You can tease out some interesting threads on fascism and feminism, too.
The year's second-tier sci-fi films had some lessons to impart as well. You can ponder more man-vs-machine themes in "Terminator: Genisys," or the perils of genetic engineering with "Jurassic World." For social engineering, there's the teenage wasteland triptych of the new "Hunger Games," "Maze Runner" and "Divergent" installments. Young adult dystopia is, evidently, always in fashion. Oh, and don't forget to get small with "Ant-Man" -- the year's most surprisingly fun sci-fi movie.
