The first season was mediocre. A bit disappointing compared to the book, but I thought the first season is never perfect. I had high expectations for the second season, but those were completely crushed after the second episode.

The book was not adapted at all to a TV series. Most of the TV series was plot contrivances made up by the writers. There was no fidelity to the source material.

I also question, when there are dozens of excellent and interesting monsters in the Witcher world, why make up your own mediocre monsters? Writers should play more Witcher games that are well adapted from the book.
