I just watched The Silence on Netflix.
There is a common sequence of events in all post-apocalyptic scenarios which we can use as guidance:
You’ve survived an end-of-days event or are in a film of that nature. You and your attractive partner scavenger through the ruins dodging some threat or other.
As you venture further afield you both wonder if you are the only two people left alive.
You begin to lose all hope of ever finding another living person. One day, you happen upon a man. He is friendly, happy to meet you and is eager to help you.
