I just finished binging the first season and I am so pleasantly taken aback by how good it was! I had no idea about the book either, the plot was fresh and suspenseful and riveting. Many others have already stated how breathtaking the entire setup is and I am in emphatic agreement with them. The mood, the pace, the entire cast, music, the story with its explorations of human limits without any overbearing moral compass. I suppose I'll go read the book too sometime, but I doubt any core sentiment has been left out. A very lyrical show, poetic and lyrical. Excellent.
