I was really taken by this one. The framing device of the master storyteller was charming and gave it a sense of scale and emotional depth that it wouldn’t have otherwise achieved. It enhanced the Ancient Chinese setting and harked back to Marco Polo - a story which has always fascinated me. The many Cindys were used to good effect and I loved the way that The Doctor and Gabby made their way beyond the damn and infiltrated this amazing environment. The world felt rich and “full”. I was so swept up in the story that I was even able to forgive it it’s technobable-filled conclusion. Had it been able to stick the landing with a more authored ending I think this would be an all time classic.
