After almost two decades and regular cast change-ups over the years, people are still very much invested in “NCIS.” Parade credits the popular series’ interesting plot lines, crimes, and fun characters as part of what makes the show so addictive. Despite heartbreak over the quiet exit of Special Agent Gibbs, fans have responded positively to the addition of actor Gary Cole’s character Alden Parker, reports Outsider, and seemed to enjoy how he shakes up the original crew.
In a Reddit thread, people attributed the show’s staying power to its realistic portrayal of character growth. One user commented on Special Agent McGee’s character arc specifically, writing, “I think the biggest change is McGee … he goes from probie/goofball to presently mini-Gibbs … remember he’s now 16 years into the job and in most real [government] jobs the upper ranks would have aged out/promoted out/transferred out.”
Another this user pointed out the differences in “NCIS” alum Tony (played by Michael Weatherly), writing, “I just started watching the series from the beginning (having started late) and I’m enjoying it quite well. Tony is so different in later seasons compared to him in the beginning.”
