As a massive fan of the book I think this series definitely did it justice. While they did have to change some bits to make it more suitable for TV they didn’t take any of the essence away. I really hope they can do a season 2 with Commander Yai (but without the ridiculous moustache) and flesh out the ending a bit more.
Overall the actors and writers did a great job bringing this book to life, if you haven’t read the book, I definitely recommend you read it because it gives more details, especially the second part and the ending.
