Doctor Who - Season 8, Episode 12: Death in Heaven
Trailer
When a dinosaur materialises alongside the Houses of Parliament in Victorian London, the Doctor';s old friends the Paternoster Gang are relieved when he arrives, seemingly to deal with the creature. However, time is against him as he must embrace his latest form in order to conquer a sinister threat lurking in the background of events.
This finale felt lacking, and part of that feels intentional, because surely some threads can be reintroduced in the next season, but some of that feels like the effect of some unfortunate plot holes.
