French television has a knack for doing more with less, and The Tunnel is a prime example. It's currently available in Australia on Amazon Prime Video, and in the US on PBS and Thirteen, so there's no reason to keep putting it off. A 7/10 rating means the audience agrees.

The Tunnel follows a path that stands out in a crowded field. The plot follows detectives Karl Roebuck and Elise Wasserman working together to find a serial killer who left the upper-half body of a French politician and the lower-half of a British prostitute in the Channel Tunnel, at the midpoint between France and the UK. They later learn that the killer—who comes to be nicknamed the "Truth Terrorist"—is on a moral crusade to highlight many social problems, terrorising both countries in the process Stephen Dillane and Clémence Poésy lead a cast that brings real weight to the material. The series ran for 3 seasons (2013–2018), building a story that gave its audience time to invest properly.

Perfect for viewers who think they've already seen all the great crime dramas. The Tunnel is the one that tends to prove them wrong.
