Personally Iliked it for the most part. As a huge fan of both the books and the games I thought I was going to despise everything about this show. In all reality though there wasn't anything just show ruining in it. The dialogue was a little wooden here and there, Geralts armor looked fake in a few places, but the story was impressively spot on. The actresses and actors were on point, the action scenes were well shot and cinematography knew what it wanted to do and did it well.
So in summary it was well done for being the first season of a new show that was adapted from a books series that also has a massive fan base from the games.
