I think that if you haven't read the books, then the viewing experience is much better. But I would definitely recommend checking out the books. It enriches the experience.
I know that there are limits to novel adaptations, but one also has to be careful not to deviate too much from the original tale. I think that the book explored the relationship between men and women; between cultures and sub-cultures; and the socio-political intricacies of magic in a more intricate and thoughtful manner.
It's still a good show that will mature and grow. So I look forward to the next seasons. 👍
