Well, they did an interesting take on the story: instead of following the books too closely (gosh, the first book is a collection of short stories without Ciri and Yen, would be enough for two seasons without getting to the main story arc) they decided to give us an introduction to the main characters, the main story line and the world - a lot for 8 hours. Some episodes feel a little rushed, some stories are fleshed out more than in the books (Yen's story). Overall not as dark and cynic as the books (where the monsters are usually not the monsters), but I'm very eager for the next seasons.
