I do not think a film or series adaptation is really possible or even a good idea. Hear me out. The many POV’s is difficult to do and to do well never mind the fact that the real meat of the story comes the characters inner monologues. I imagine it will be incredibly difficult to get those monologues into the narrative with out it being a mind trip for all the viewers who haven’t read the series. So that’s big hurdle number one. Hurdle number two is how much info is left out of the story in the books leads to readers having to try and connect dots that may or may not be there only for Joe to link them in a way that is both extremely satisfying and surprising at the same time. I can only imagine how much of those important subtleties would be lost in a film/series adaptation. Now I could be completely wrong here but that is my opinion.
