What difference does it make? You had the perfect story as written. Script it. Cast it. Shoot it. Nope, much better to write it completely new, based on a memory of a drunk man in a bar relating the general gist of the story he heard 3rd hand from his cousins, roommates, neighbor.... I think Muppets make an appearance in season 5, or was it Alf?

They had the perfect script, but Rafe wanted to "make it his own". The Wheel of Time television series is a fascinating example of how someone can read books then talk about them in a bar, overheard by another patron, recounted to a neighbor, re-invisioned by a 3rd cousins nieces grandfather who can get $$$ out of Jeff Bezos to do whatever the hell they want to.
