Overview
- The five-episode UNIT-led miniseries concluded on BBC One and iPlayer on 21 December after a two-week, double-banked rollout.
- The finale drew an overnight UK audience of 1.79 million, broadly consistent with the previous episode, with consolidated figures still to come.
- Co-showrunner Russell T Davies describes the series as a complete narrative with no confirmed plans for continuation.
- The production was commissioned under the BBC–Disney co-production and distribution arrangement, which has since ended, clouding prospects for further installments.
- Creators emphasized a deeper spotlight on Kate Lethbridge-Stewart away from the Doctor, while commentators praised the tight, five-part format reminiscent of past Whoniverse event series.
