Those who have read the novels will find this tv series an insult to the source material. Complete disregard to the original fans. It wasn't just altering minor details to make Witcher fit into big screen medium. The story, characters, world and its customs and rules had nothing to do with an original story in the novels. It's like Netflix used Witcher brand to make it interesting for an average viewer and created their own story and just named characters like in books. If it wasn't named "Witcher" no one would have paid attention to that failure.
