I feel like the changes to characters are really large. The feelings I have from each character in the books and the show are not close enough to be the same character. Mensa is so much more emotional and reactive in the show than she was in the books, but I like both. Murderbot is much more human than in the books, there is way less internal monologue, so it feels very different, but I still love the character in both. Same for all the rest.

As for the story changes, so far it seems good in terms of changing just enough to make it fit for TV rather than doing something insanely different with only a passing resemblance to the books. I like how the violence is shocking, sudden, and really limited. In the books it is not the whole story, one gory moment after another, and I was worried they would get sucked into the trap of violence being attention getting and shocking and therefore needed in huge quantity.

The visuals are excellent. From a purely technical perspective they have done a great job with making something easy to look at, enjoyable to experience, and mostly visually consistent. There have been very few moments where the colour balance is skewed weirdly, where the lighting requires adjusting the screen, or where the volume levelling was terrible. Great production quality.
