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.
More like rebooted 3 times- remember Terminator Salvation?
Coincidentally, that was the only post-T2 movie with any potential to be interesting since it was something new and not a rehash of the same old time traveling assassin bot plot but it's a shame they completely fucked that one up too.
