I definitely enjoyed this more than (Surface Detail)[https://book.dansmonorage.blue/book/18939]. If nothing else, it is notably shorter, which suggests an instance of "established authors need editing too".
Banks does love to shock, and loves to write "cinematically", which occasionally a bit tiresome.
While I think describing the Culture series as "Literary Science Fiction" is a bit of stretch, there are some interesting big picture ideas, and some of the characters have some depth, or at least some interior life. The choice of having a "bad guy" protagonist already elevates it beyond a lot of more pulpy SF.
