This episode has a lot of really great stuff in it. Jodie Whittaker has a wonderful scene with a woman who survived the murder of a child as well. It’s a really sensitive and heartfelt scene. And then later, there’s a wonderful counterbalancing sequence involving the Latimers that’s one of the most hopeful scenes of the entire series so far. Pauline Quirke is really brilliant as the mysterious Susan Wright; she’s been uniformly good so far, but this episode lets her take center stage for a bit and she’s really amazing. And kudos for the episode ending, which is intense and gripping. And features, by the by, the best acting Tennant’s done in the series so far. It’s a moment you see a lot in movies/television and performers rarely manage to make it feel real, but Tennant does. That final close-up of him is brilliant. All in all, this is an absolute return to form after the slightly disappointing episode 5. It may, in fact, be the best yet. 4 stars.
tl;dr – after brief detour, series returns to form with a bang-up episode, featuring performances better than any episode so far, wonderful plot twists and a crackerjack ending. 4 stars.
