According to the showrunner, the series is designed to be accessible to viewers who're entirely new to the world of the Witcher, but enjoyable for existing fans. There's also been some substantial changes to the plotting (which is based entirely on the books, rather than the video games) to inject interest for book fans.
Q. The Witcher games and books are very popular, and yet there are still many people who are unfamiliar with this world. How do you make this accessible for new audiences?
LH: The most important thing that I set out to do was the make the show surprising enough for existing fans but also I didn’t want to dumb it down for fans who have never experienced this world before. I am a firm believer in challenging audiences and I think that they can keep up. Audiences are incredibly savvy. One of the very early decisions we made is that we don’t subtitle anything, we don’t add chyrons in, we don’t tell you where you’re at every moment. I think it’s much more fun to watch the first few episodes and not realize you’re on two separate storylines until someone who is dead is alive again and much younger. To me, it’s just about telling the story in the best way and having faith that people are going to hang in and be there for it.
