Sci-fi genre
The Science fiction genre has developed a lot over time with more and more iconography distinguishing it from other genres. When we think of Sci-fi futuristic technology, spacecraft, dystopian/utopian societies often come to mind in a palette of greens, greys and whites.
Sci-fi movies often follow a hero narrative through a character arc as they try to right an evil. The sci-fi genre was originally quite a male demographic but, the increase in female leads in a sci-fi role has helped gained followings from women of all ages and is now one of the most popular genres as it takes fantasy to another level.
The Science fiction genre is also more prone to having a cult-like following due to their alternate realities, world building and in-depth characters.
Sci-fi is often a reflection of society and the ways in which we could end up if things keep changing as they are or if technology develops. Sci-fi often switches genres with elements of romance, comedy and more recently western with the HBO show Westworld. Because of this nature the Sci-fi genre is always changing and adapting in new ways.
