I believe this show carries same burden as Game of Thrones, bad writing. I love every person on the cast but the way of building their characters was poorly written. As non-reader of the books, i could not understand the world that show takes place, which kingdoms are better, who rulles this world? Why witcher drink this black potion and get black eyes? I mean i can assume why but they didnt give us anything. All season was about introducing characters but it wasnt enough.
