A confident, even audacious opening to season two of this pitch-black comedy-drama. Via an entire episode dedicated to another character (Naomi Ackie's blank yet somehow remarkably expressive Bonnie), we are filled in on a whole new strand of relevant backstory and yet, deliciously, hardly any the wiser about where the series might be going. It is a beautifully observed little tale that pulls off the admirable trick of being desperately bleak while remaining very funny indeed.
