This is a really neat new show. (newish) I love monsters and fairies and all those good spooky magical things, and even more so, I love a setting that places these things in our real world. So first off, the world setting is really interesting and I'm always hungry for more lore. The story is also really interesting. I'm engaged and curious what will happen next, from the small dealings between characters to the grand overall scheme.
I love the main character because he's so immensely broken, but there's hope still in him. He's complex and you can tell the writer poured a lot of his own soul into him. Also, I'm honestly very impressed by how many characters this show seems to have, and yet doesn't manage to be confusing. I've heard the creator say he's run out of voice actors, which I find surprising because there's always a new and interesting voice. I suppose that means the writing and the voice acting is really good. Also the sound design is really fun and well done.
