A semi-sequel to the "Doctor Who" story 'The Daemons', this explores the nature of the Daemons and their connection to humanity. Both Kate Lethbridge-Stewart and Capt. Douglas Cavendish (played by husband and wife team Miles Richardson and Beverley Cressman) return from the earlier film 'Downtime', although their characters are expanded upon perfectly as this is very nearly a two-hander. That's not to say there's no plot - there is, a complex one which begs a sequel. On the basis of this such a sequel would be highly welcome - the direction is the most assured of a "Who" spin-off so far, the picture quality surpasses anything we've seen before, Alistair Lock's score is suitably chilling, and the cast (including the late, great Michael Wisher's son Andrew) are uniformly excellent. There are nods to "Doctor Who" (I'd give details, but the joy is in spotting them alone!) but this is strong enough to stand up on its own, easily bettering the story which inspired it (this is far more atmospheric for one thing, and the ending more logical). Credit is due to both David Howe and Keith Barnfather for this, and one hopes it won't be long before they're teaming up again, perhaps for 'Daemos Dawning'?
