They're great fun.
I was disappointed with Martha Wells' most recent book though. I won't spoil it, but it came down to me never emotionally connecting to the main character, and too much worldbuilding having been done for one book...a lot of build-up that goes nowhere.
I haven't read her non-Murderbot books, so at some point I imagine I'll be curious enough to go back and see if Murderbot was just something that hit a zeitgeist, the right topic at the right time, or if Witch King simply a weaker offering even compared to the pre-Murderbot stuff she's done.
