Black Earth Rising 9pm, BBC Two
Kate realises the danger around her is very real. Nevertheless, she presses on, searching for the old case file her mother compiled, then heading toward the heart of the case, and of her own history, by journeying to Rwanda for the first time since she was an infant. Tonight’s episode comes bookended by two scenes that are ominous for entirely different reasons, and fits in an action-movie scuffle and chase in the middle, spiced with some very odd touches. Yet what really marks this out is its intelligence, and how it credits viewers with intelligence, too. The complex plot about the Rwandan genocide offers a lesson in recent history, but also in drama. Few series have so heroically disregarded focusgroup thinking about what audiences will sit still for.
