From memory streaming services greenlight on a per season basis. While pre 2010s you would be greenlit for 2 or 3 seasons and you would hear after the first season of you would be renewed.
This is actually a well done scifi anthology series that respects many of the themes and motifs present across Philip K. Dick’s works.
While I have not read the short stories (I've mostly read his novels; about ~20 of them), many of the episodes have that psychedelic edge that Philip K. Dick is known for.
