If there's any series/franchise ripe for a true comeback: It's The Terminator.
It's pretty widely agreed that every movie after 2, which is over 30 years old now, kinda sucks to varying degrees (Tho 3 might have it's moments).
They've tried to soft-reboot it not just once, but twice, both being pretty abysmal failures.
In the right hands, I think it's very possible for there to be another critically-acclaimed and successful Terminator movie, I don't think it's impossible.
Terminator 1 was about fighting off a creepy superhuman stalker.
Terminator 2 was about fighting the police with your guerilla revolutionary mom and robot dad.
