I enjoyed the first season. It's pretty much average. I would say a 6 or 7 star. The storytelling is a bit convoluted, and the timing between switching from character to character is a little to long. The anachronic timeline was a plus, in my point of view.

The second season was a step down. It kept the convoluted storytelling and lost the "surprise element". I mean: they could have been more epic while using the cliffhangers from last season. Also, Geralt is to underpowered, or doesn't show his skills enough. That's a waste of resources. After season 2, I say it's middle range, 5/10. Maybe they can step it up a bit if we see a 3rd season.
