It's definitely continuous in tone with the last seasons of AT, which is why I think it's an Adam Muto thing. But it feels like it's turned into Doctor Who. (Or what I imagine Doctor Who to be now; I haven't actually watched in a while.) Like, it's fine when you have a world with no rules as to what's possible (because of magic and/or advanced science) if that world is silly, but it makes it hard to generate dramatic stakes if every obstacle is magic bullshit and every solution is also magic bullshit.
