I like The Witcher's humor and action a lot. The first episodes are kinda bland but still come with some cool scenes. From ep. 3 or 4 on the show becomes very enjoyable to watch. My points of criticism are related to storytelling (portrayal of different timelines; big gaps between episodes' plots) and the handling of characters (not enough background info, I don't really feel attached to anyone). This show clearly does not want to be another Game of Thrones (Netflix executives probably do anyways) so better don't compare them. It's mainly focused on action and small adventures rather than on great character and story arcs.
