If I reverse the first two words of the title (and call the question mark to attention), it removes all uncertainty, but for now I’m on the fence and asking. I’ve already reached certainty with both spin-offs (the oldest many years ago, the younger sibling just last year). Now, either I might be over their parent, NCIS, or just maybe the show itself is over.
I sometimes get the sense I’m more attached to the idea of over than many. I’ve mentioned more than once that I try to look forward, and around, rather than in the rear-view mirror. I’ve also mentioned how a primary ask of mine for stories is: “Take me someplace new.”
Nostalgia never had much pull for me, nor did more-of-the-same once a story has been finished.
