I think this is clearly a case of not every show needs a reboot.
On the contrary, I think that updating to current times and issues is a good thing. The original series did a good job, for its time, in opening up perspectives. That's a worthy pursuit.
My skepticism is that NBC has had a really crummy record with scifi shows for quite a while now. La Brea. Debris. Powerless. Heroes Reborn. Emerald City. Constantine. Believe. Awake. Do No Harm. Dracula. All cancelled after one season.
They've had
Manifest run for three seasons, though I didn't like it much. They had
The Good Place, but that's more because Michael Shur is awesome than any merit of NBC's.
One totally awesome show they had,
Timeless, they went and cancelled, it got revived for a second season by, of all things, Sony pushing for it, and then cancelled again (but at least gave it a wrap-up TV movie, for which I was grateful).
