I think it's too easy to say NA is similar to "Highlander," simply because its lead character is immortal. While McLeod cannot die unless beheaded, he, and his fellow immortal Nick Knight, are immortal primarily defined by their supernatural natures. The great appeal of John Amsterdam (or York, or Dutch, or any of his other aliases) is that he is a relatively ordinary man who, by virtue of having lived in New York since the 17th century, has learned much and experienced more. None of us is likely to picture ourselves as McLeod or Knight, but practically anyone can imagine that given the right circumstances, we could be John Amsterdam. He is extremely human, not at all superhuman....except for that one thing. He cannot die, not until he finds and commits to The One. It is refreshing to find a sci-fi story framed in a police setting in which the crimes are the least interesting parts of the hour we spend with him. We want to see more of John with his son, Omar. We want to go back into his past. Unfortunately, I at least have no desire to see him further his relationship with the woman he believes is The One.
