Science fiction is a genre of fiction that features imaginative concepts such as futuristic settings, technologies, space travel, time travel, and alien lifeforms. It often explores themes of good versus evil, oppressive societies, rebellion and conflict through entertaining stories that also provide commentary on modern society. While big companies typically produce science fiction films, the genre appeals to broad audiences by transporting them to new, fascinating worlds without boundaries, and can inspire younger generations through inclusive narratives and optimistic visions of the future.
