I am currently watching Altered Carbon on Netflix, which is based on a book trilogy.
The story of the first season by and large follows the storyline of the first book, Altered Carbon (despite a couple of radical changes when it comes to the characters' background and relationships).
At least based on being set on Harlan's World and dealing with Quellcrist Falconer's return.
Editorial: What a shock! The precious second novel! IMHO the most interesting one in the trilogy, because it contained more info about the mysterious Martians than the other books if I recall correctly, and because it provided for quite a change of scenery (a warzone and a spaceship, rather than just a crime-ridden megacity all the time).
Have there been any statements by the producers on why the second novel was not adapted into the series and we skipped right to something vaguely reminiscent of the third book instead?
