This series is well written and cast. We really enjoy the lead character, John Nolan, and the "family" he has bonded with. The central characters look out for each other in realistic situations. However, I gave the series 4 stars because the long term evil characters are becoming tiresome. We skipped a few episodes before that serial killer was eliminated. Now the Elijah Stone character is winning over and over. This situation is not entertaining. If I want to see bad guys constantly succeeding, I can watch the news networks.
