I think NCIS has run its course. Although Gibbs and McGee still carry the show admirably, Ducky's wisdom and humor have been sorely missed due to his frequent absences. Bishop and Torres are no substitutes for Tony and Ziva, the Jack Sloane character adds nothing, and the new lab tech, Kasie, is just plain insufferable. What a huge casting mistake there. I loved you for a long time, NCIS, but you just can't hold my attention anymore. It's time to close up shop because the magic and the cast's chemistry are gone.
