If you're an avid fan of the Witcher universe, don't bring the expectation that the show will stick to the source material 100% because a lot is curated so it is presentable in the TV format. With that being said, Henry Cavill manages to capture the essence of Geralt's character extremely well and is definitely the highlight of the show. The acting overall is far from terrible as some reviews seem to suggest and other than the obvious gaffes of casting such as Fringilla Vigo being played by a black actress and some other black characters showing up in a universe that's supposed to be set in medieval northern Europe there isn't much to nitpick at.
