Murderbot remains a really interesting series and, in the great tradition of Martha Wells, it's easy to forget that she's doing something really interesting in the genre because of how understated her writing is.
Her take on AI is the mark of a sea change in how we think about artificial intelligence and her ideas of sentience are fascinating...but easy to miss because it's also a plot-filled sf novella. It's a book that rewards both the quick read and the post-read thinking about it.
