YMMV: Lucifer's Hammer

  • Harsher in Hindsight: at the very end; the heroes successfully defend the last operational nuclear power plant in the world from the cannibal environmentalist fundies(at the cost of their Gadgeteer Genius - he was diabetic, but chose to make mustard gas to kill the cannibals instead of insulin), but it would only take one lucky mortar shot to destroy the plant, and the only way to keep that from happening is to hunt down the fundies and either take all their weapons or kill them all. To save civilization, they have to fight The War on Terror, and be willing to commit genocide if their enemies refuse to surrender.
