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.
I had a spec script for a serial killer murder mystery, where the twist is that there's an alien killing people too, and the detective starts to realize that, but the colony authority decides it's just the serial killer, and the detective and the serial killer and the alien all get caught up in this three way confrontation at the end. Probably the with the serial killer and the detective teaming up to kill the alien, leaving the serial killer ambiguously dead and the detective ambiguously infected.
