It's not easy to create a supernatural setting that feels fresh. The Rook is the most successful approach since Sense 8. Most importantly, Gestalt is the most original and hypnotizing character idea since I cannot even remember (I guess you can argue "ever"). I am disappointed that they are not the main character, and this is my main complaint: I find Myfanwy one of the least interesting characters in the story. I still really enjoy the show, but it's tailored for a specific audience that enjoy alternative supernatural stories. If you enjoyed Mysfits, The Umbrella Academy, or Sense 8 - I cannot recommend it enough. The story unfolds slowly, but it is way more subtle than I expected from something based on the book classified by many as YA. Gestalt alone make me want to know what happened next.
