LIGHT SPOILERS FOR THE WHOLE SERIES
Having read the series, I was at first a bit put off by Murderbot’s interpretation to the screen. It’s a little cheesier so far - the survey crew for example. And I never got that Murderbot was so outwardly awkward when dealing with humans. It hates it, sure, and sometimes it slips up and lets its emotions show, but typically it was capable of being socially competent (as in pretending not to be rogue - and eventually pretending to be human). I don’t recall the “speech” scene happening in the book. There are also a few lore changes so far.
That being said, I’m enjoying the TV series as its own thing. But I definitely recommend the books to anyone who prefers hard sci-fi.
