NCIS: Los Angeles is not typically known for wading into This Is Us territory. After all, it's a hugely successful procedural drama about the high-stakes world of a division of NCIS (Naval Criminal Investigative Service) that captures dangerous criminals who pose a threat to United States security. In other words, storylines about adoption, acting, or weight loss typically aren't part of the narrative—and that's totally fine. It's a hour of escape each week into a world that most Americans don't experience. Still, throughout the show's eight-year run, the series—at its core—is about four unlikely special agents who truly are the epitome of love and family. From the bromance of Sam and Callen to the romance that is Densi, the show has succeeded because of the characters and the actors who play them.
