...some comments. It's a generic fantasy world. Writers didn't really dig into the story, they seem to have went through a wikipedia synopsis of the books. That does not mean it is a terrible show. A little rought around the edges. With some very good qualities.

Cavil is amazing, and he's not alone. Lars Mikkelsen who played russian president Petrov on "House of Cards" is also great (and completly different from his books version! Kudos to writers on that one!), very good actor. Joey Batey(Jaskier) and Anna Chalotra (Yennefer), and several other did a great job.

Now for the criticism. Casting is not 10/10, despite some very good choices. Locations seem empty and generic. Half the show seems to take place in a ball room, with no food or drinks or decorations. The pace and storytelling is not great, and a lot of people seemed confused, if they weren't already familiar with the story. If they were, they were complaining on too many liberties that writers took while adapting Sapkowski's story. CGI was sub-par, probably from budget restrictions. In a world with dwarves and half-lings as two important and distcint races of the genre they seem identical and dissapointing levels below their LotR counterparts (who are almost 2 decades older. Yikes!)

All-in-all it's an ok show. But there are certainly are better things on Netflix, and comparing it to GoT is atrocious, even if you hated the ending. Just don't fall for the marketing campaign and people claiming it's "the best show ever to hit the screens". Watching Cavil is the high point and watching it just for him is enough to enjoy your time.
