DA My main issue is everyone is a lot less competent than in the books - I think most of the other changes are understandable to make it work as a TV show. Like, Murderbot does come off more emotional but that's because we can actually see its face, not just read its denials. But in the book there's a lot of Murderbot either saying it's incompetent or implying the crew is, and then we get to see them actually being super badass. In the show there's a lot more of everybody just bumbling around for real.

Also they've been pushing hard on the "Murderbot is ace because it doesn't have genitals" where I feel like the books were always careful to say Murderbot would be ace even if it was fully human, just like some humans are. And that leaves a bit of a sour taste.
