When I say "or not" I mean shows that haven’t been officially confirmed as being discontinued and could come back, such as, Mindhunter.
The topic covers shows that you know have no chance of returning because they are so old now, but you would have liked to have seen a proper finale. The Sarah Connor Chronicles for example, however, they do have time travel though so…?
And of course shows that have been confirmed as being discontinued even after one series and left us with a cliffhanger such as, my first mention, Archive 81.
So off the top of my head…
Archive 81 (This didn’t even get a chance)
Hannibal
The OA
As mentioned, Mindhunter
Spinning Out (I love figure skating)
The Sarah Connor Chronicles
Heroes (Heroes Reborn was not good enough for me)
Lie to Me
Jupiter’s Legacy
Suspicion
I know there are more that I am not remembering right now, but these are what came to mind.
