One of the best shows Netflix has ever made. A dark fantasy with masses to say about the true nature of evil. By focusing on the Skeksis and their motivations and interactions it creates some incredibly chilling scenes that it somehow gets away with because it's a puppet show. You couldn't make this with live action, it would be too harrowing, but because it's puppets they manage to get away with concepts like genocide, torture, appeasement, colonialism and survival of the fittest in a show your kids can watch.
Strongly recommend.
