Most critics come away shaken and impressed. The reviews agree that Richard Gadd’s account of being stalked is honest to the point of discomfort, and that its refusal to make him a tidy victim is the point rather than a flaw. Praise clusters on the fourth episode, which several reviews single out as the hour dealing with abuse and assault, and on Jessica Gunning’s performance as Martha, which even the sceptics admire.
The reservations are about shape. Two of the eight dissent sharply, both finding the series gruelling as drama: The Telegraph argues the voiceover gives away its stage origins and that it lags, while The Guardian finds it relentlessly bleak and frustrating in scope across seven episodes. The Times, broadly positive, also thinks it runs a couple of episodes too long. The spread is wide, with nothing in the middle.
