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.
I think it is trying to tie in the strands of events leading up to the start of Witcher 3. It is really great and it makes the viewer really think instead of signposting everything. I just finished the season, and I am HYPED for the next season!
