Superior to Angstrom.
The second episodes of a showrunner say so much about their vision. For RTD, the question was 'what if the Earth was consumed by a ball of flame'? The End of the World effectively introduced the Time War, and changed the show forevermore. For Moffat, the question was 'What would a corrupt far-future starship version of Britain look like'? The Beast Below was a heady, political episode that set up a difficult moral dilemma and pondered on the nature of memories.
For Chibnall, the question is...'just who are Angstrom and Epzo'?
One wonders what the pair of them will get up to next.
