Well, that was another short-lived series for NBC.
Right now I'm rewatching The Event which after only one season was cancelled by NBC,
It was aired more than 5 years ago, I clearly remembered the last scene, quite a cliff-hanger.
So I watched that final episode first, and I found something about a virus, a pandemic, which I have heard about recently of course.
But in this show, there is a group of "people" who released the virus on purpose.
This group of "people" want the virus to kill mankind to make room, so they could bring all of their people to Earth.
I seem to remember that the writers read the writing on the wall, and as they learned the show was doomed to be cancelled, they decided to make a change for the last episode,
The virus thing didn't work out,,, the aliens were able to bring all their people, well kind of, they brought their whole planet with its moon and all, and parked it right next to Earth....
But I digress, sorry, my point was, another series with a short life on NBC, - I am used to it by now.
