This story is an instant favorite. Two of Big Finish's strengths are 1) providing more depth to classic characters and 2) being able to seamlessly blend the classic era of Doctor Who with the modern one. This release does both perfectly, and it's a testament to the powerhouse of the Season 19 tardis team that they make up the entire cast of the episode! We get a fascinating examination of how each character would react to a nightmare world of their own making, and the trippy nature of the dream crabs propels this story with ideal pace. For me, this has established itself as one of my all time favorite Doctor Who stories, ever!:)
