'NCIS' Should Have Ended 5 Years Ago After Its Game-Changing Exit

As NCIScontinues to air, fans of the series are all missing the void left by the most iconic and important character from the show. At the conclusion of Season 19, Leroy Jethro Gibbs, the supervisory special agent played by Mark Harmon, bid farewell to the agency with a retirement to idyllic Alaska. The significance of this departure could not be understated: Harmon was one of two original regular cast members to complete 19 seasons and was the foundation around which the rest of the show was built. Gibbs first appeared in the backdoor pilot for NCIS in 2003 as part of the JAG series and has appeared in every season since.
