The coolness of Dark is not just in its Germanic dreariness but in the story’s deliberate time-bending trippiness that feels more sophisticated than much of what I’ve seen on American television and avoids being as manifestly geeked out as Dr Who. At its core, Dark is the story of disintegrating kinships in a small town that is also home to a nuclear plant. Children are disappearing, just as they had 30 years prior, and sadness and madness have taken residence in the remaining spaces. This fairly miserable storyline is given greater spark by the mysterious cave just outside of town that yawns and growls and transports unwitting townspeople into the past and future and generally menaces and confounds. Like I say, cool stuff.
