So I didn't even know there was a book series of the Witcher until after beginning the netflix series, but just from watching the first 3 episodes I can say that I am very pleased with the show so far. I am very familiar with the games so watching geralt run around killing monsters in live action is pretty bad ass. Im not normally a fan of fantasy tv shows (didnt care for GoT) but i absolutely love the witcher so far despite it being set in a fantasy setting.
