Let me start with I have never read the book, so I came in with a completely empty mindset.
I wasn't sure what to think at the beginning, but found myself watching multiple episodes in a row until i'd watched all 13 in a 24 hour time period.
There was/is so many possibilities of what could happen during every episode, with only a handful of moments that I foresaw. Really was surprised by this series.
For those who haven't watched it and are in search of a time filler, give this a watch.
