Dark (2017)

A missing child sets four families on a frantic hunt for answers as they unearth a mind-bending mystery that spans three generations.

Yellow Raincoat Significance: Jonas's yellow raincoat is a constant throughout the series, symbolizing optimism and serving as a visual identifier for his 2019 version as he travels through time. The color yellow also increases visibility in dark areas, which is fitting for Jonas's difficult and dark time travels.
Biblical Names: Many main characters have Biblical names with symbolic meaning. For example, Jonas shares his name with the biblical figure who was swallowed by a whale, reflecting Jonas Kahnwald's struggle to accept his destiny.
Casting Perfection: The casting directors for Dark were praised for finding actors who closely resembled each other across different ages. Simone Bär, the casting director, received immense praise for her work on the show. The casting was so accurate that some viewers initially believed the same actors were used with makeup to portray older versions of the characters.
Showrunners with Creative Freedom: Dark is unique because it had two showrunners who had 100% creative freedom to tell the story as they envisioned. They had a shared vision and aimed to bring a cinematic quality to television.
Visual Storytelling: Cinematographer Nikolaus Summerer used specific techniques to distinguish time periods. For example, the series employed the ARRI Alexa camera with a 65mm lens to soften faces in 2019, similar to the movie Joker. The use of color palettes, lighting, and editing contributes to the show's intense and somber atmosphere.
