The four films you mention have served as the basis for any story based on cyberpunk; perhaps The Matrix is one of those productions that fed on the other three films, but there is no doubt that the ingenuity of creating all those stories is in itself a path that should be traveled by those who want to know more about this genre.
I have a soft spot for Blade Runner and I hope that the next series that will surely serve as a sequel to "2049" will also be as good as the two films already released.
