Star Wars, Star Trek, Stargate, Matrix, Blade Runner, X-Files etc.—There are a lot of great, big sci-fi movies & tv shows. So, it’s very difficult for a screenwriter to create unique sci-fi without someone says “aargh, you stole it from [put here a famous sci-fi franchise] …!” or put an overused cliché in it.
I wanna write science fiction. But there are stories which are so overused that those are a cliché. For example, the strong A.I. which bring down the humanity or want to be a human.
Do you have any tips how to write unique sci-fi?
