Seldom if ever have I seen so successful a translation from book to screen as was achieved by the now-ended program, The Expanse. Covering the first six in an excellent nine-book series by James S.A. Corey (pen name for Daniel Abraham and Ty Franck), who were deeply involved with the program as well, the show stuck pretty close to the books, but never hesitated to make changes when something that worked on paper might not have on screen. (Best of all was the "promotion" of the minor book character Camina Drummer to a major character in the series.)
In any case, the show concluded this week, and I have some preliminary thoughts about it.
