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 French police procedural following the overlapping worlds of police, prosecutors, lawyers, and judges in Paris. The most detailed portrayal of the French legal system in drama, educational about inquisitorial vs adversarial legal processes.

Exceptional craft across eight seasons. Better than comparable American procedurals in institutional complexity.
