I've just started the 1st of the 3 books, it's not particularly thick so not sure how big they could make it, and netfix et al seem to do shows for at least 3 seasons before cancelling. They could do what they've done to Foundation and make a series of the exposition, the first season has dealt with the fall of the empire, which takes up about 2 pages of the book and is the best part imo, (mainly because Lee Pace absolutely nails the part of a God Emperor). Sadly the rest of it has been ruined in a typical Apple TV woke fest.
