I've only watched a single episode so far but I thought they are doing a good job! I am curious to see where they will take it. While the game obviously has a main story, I think that one of the things I enjoy is the freedom to pursue general bounties and just live the life as the Witcher. While not great for a narrative show, I wonder if they'll incorporate some of those elements.
I do think the fighting is pretty impressive as well because it feels similar to the videogame mechanics but is also realistic, which is nice.
