I'm about half way through, and after initially being like "oh god, why?" after the first episode, I've considerably warmed to it. Its not perfect, but its moody and fun. The Sabrina character is utterly infuriating, but I'm 100% here for Richard Coyle channeling Bela, Michelle Gomez and Tati Gabrielle. As you said, its not amazing, but I'm still watching.
ah its grand. silly but grand.
