This week, I watched one of my favorite series of science fiction novels be adapted into a TV drama by Netflix - Altered Carbon - and while the adaptation wasn't bad, and the show was entertaining as pure popcorn - it was soooooooooo 2010s in one respect. They absolutely could not resist adding to a beautifully plausible book, unlikely personal contrivance. Characters that are not related in the books are now siblings, just for extra feels, when the book knew where to draw the line to maintain a natural feel. Characters that plausibly exist as different personalities, are now rolled into one, where they are distinct for good reason in the novels. Someone going into it blind is still gonna enjoy it, its the best cyberpunk series we have perhaps ever had on TV, but when every dime-a-dozen genre show from the Arrow-verse to random ABC or SyFy's stuff foists unlikely contrivance into plots, it makes you really wonder whether writing rooms are somehow horribly pressed for time that they can't think of a more likely reason for something.
It's funny you mention that. I just watched Altered Carbon last week, and did love it, but have never read the books. I did read The Expanse before seeing the series, however. The one thing they really changed which works much, much worse than the books was the decision to have the Roci crew begin as near strangers who distrust each other and are always getting into fights, rather than a team that works together like a family (where the conflict comes from the outside - other than Naomi/Holden relationship drama). Again, this seems to be basically praying to the alter of "Modern TV" where the characters need to have interpersonal drama in order for things to be interesting.
