Dark

In the German town of Winden, the disappearance of two children in 2019 triggers an investigation that links four families across a time corridor connecting three different eras: 1953, 1986, and 2019. This German series by Baran bo Odar and Jantje Friese is arguably the most rigorous and coherent portrayal of time travel in the history of television. Its intricate family map, spanning four generations and multiple causal loops, stands as one of the most ambitious world-building exercises in the medium.

Dark is the most rigorous and coherent time-travel series television has ever produced. It demands full attention and rewards viewers with a conclusion that fits together perfectly. Watch it subtitled from German—do not watch the dubbed version.
