As long as they can get the ratings they will keep making them.
The planted spinoff, which will air as a two-part “NCIS” episode in the spring, will center on the NCIS New Orleans office, which handles cases from Pensacola through Mississippi and Louisiana to the Texas panhandle.

If NCISLA didn't have NCIS as a lead in it would have disappeared a long time ago. NCIS NOLO will need a very strong lead in and very poor competition to make it to next fall.
NCIS LA is NOTHING like NCIS.
I like the original NCIS Better.
And I only watch the NCIS LA because the Old Lady has these magical powers which I can not explain.
So it's a 2 part episode and not a series ?
