Viewers are raving about Channel 4's "spellbinding" mental health comedy drama Pure

Pure tells the story of a young woman called Marnie and her experience of pure O, an excruciating form of obsessive compulsive disorder that manifests itself in intrusive sexual thoughts. It's also really, really funny.
