It is hard to keep TV shows interesting forever. The show becomes gimmicky. No matter how good. People need to grow, but ratings must stay high. So people don't really grow. Gibbs can't really develop a real relationship with a woman. How long can David and Dinozzo tease each other? Abbie and Mcgee? So Abby is going to dress like that in her 40s? They just killed off Levin, Franks, Cade in 3 episodes. It hasn't fallen into the toilet like House, but I sense some shark jumping is coming. Gibbs will jump the shark in the last episode of the season.
