I finished book eight of The Expanse series, Tiamat's Wrath, a while ago and have been waiting for the last book to be published in paperback in the UK (June I think). In the meantime, the TV series grew in critical acclaim and then recently came to an end (with season six). I finally sat down to watch them all and, in a word, was impressed.
The TV show has been blessed with a good cast, good scripts and a good production. The books work particularly well because the characters work so well: you come to care about them. Happily, this is also the case on the show. There comes a point where your understanding and sympathy for the characters allow their moments of silence or laughter to say everything you need. There is plenty of action and adventure packed in on the screen, and more compressed than the the page, but the quiet moments make a lot of difference. The terrible trials and trauma people go through on the page have been translated to the screen in a very satisfying way, and a way that packs the same emotional wrench I remember from the written words. There's a lot of dross around: it is very refreshing to meet its polar opposite.
