How we stay independent. Editorial scores are not for sale. TVI may take on paid advisory or research work, but no commercial relationship buys coverage, advance access to scores, favorable treatment, or a change to a published finding. We pay for our own streaming subscriptions, and no reviewer sees sponsor data or affiliate revenue tied to a score. More about how we work →

The TVI Take

A Yorkshire detective investigates his daughter's murder and uncovers nuclear conspiracies. Named BAFTA's greatest British TV drama in a public poll, the series is a meditation on grief and Cold War paranoia that uses one father's investigation to lay bare the nuclear establishment.
