I absolutely love how they changed "Ashford" in the books from an elitist obstructive middle manager into "Klaes Ashford" - legendary OPA member, space pirate and "The Ghost Knife of Callisto".
The show really gives the opportunity to explore the individual motivations of the characters; the books are also great and they complement each other, but I feel that the books are almost too fast paced to really savour the environment and setting.
