Thanks for the feedback @Zaf. Having not played the games or read the books, I had nothing to base my opinion on other than this series.They're solid, but feel like a series of short stories than a big epic tale. Worth a read if you enjoyed the games.
I have not liked the TV series at all though, they have thrown all their eggs in the basket of "get Geralt right" and then neglected nearly every other aspect of it. Hard to criticise the acting when the script is so thin they don't have anything to work with.
Apparently Netflix gave season 2 the green light before the first had aired, they were that confident in it's appeal. Interestingly the credits for each episode lists no less than four different directors - perhaps due to filming in different locations?
