The original NCIS starring Mark Harmon enjoys one of the clearest Inner Family motifs.
The successes and failures of this “family” are visible in virtually every episode since the pilot (try your public library).
How much is this “family” a result of deliberate casting and writing? Hard to say. NCIS is also one of the best-written shows on TV. Many shows revolve around character development, sometimes entire episodes. However, “family” aspects, just below the surface can never be strong enuf to sustain a TV show 14 seasons.
How conscious is the “family” aspects among producers and writers? I assume some are much more conscious of these aspects than others.
