This post makes me interested in Ludwig I like how you compare Ludwig's tone and creativity to a “golden age” of British television, when productions seemed more adventurous and charismatic. The idea of a character like Ludwig, whose personality draws him into such a social setting as a police station, sounds fascinating. It reminds me a bit of the protagonist in the Swedish series Bron, who also had difficulty understanding her surroundings and how to relate.
It seems an ideal balance between mystery, humor and emotional depth. Definitely a production that seems to deserve more attention.
