Matches are drawn from Cinnamon DB’s emotional fingerprint — a reading of how a series actually plays rather than how it is catalogued — then weighted by shared subject, cast, creator, studio, network and era. Genres include the ones TMDB’s television taxonomy leaves out: it has no Horror category at all, so that one is inferred here rather than missing.
