I love the books of Sapkowski from the Witcher. Although it's closed in 5 books of Ciri story amended by few stories about Witcher they offer wide universe to which I like return from time to time, always discovering some new threads. Netflix had to choose a way to cut through this story and translate it into engaging experience. It's not perfect, it's not at the niveau of books, or the W3 Game. Very well filmed, sword combats are one of the best I've seen. So worth to give it a chance. What is missing from books is the unique sense of humor, witty dialogues that in Netflix case are flat and sometimes remind me of writing of my 12 years old son. So if you have some time -give it a chance. And then... if you have even more time - go for the books. You won't regret it (p.s. the 1st part is a bit difficult, but don't get discouraged)
