My favorite thing about Sci-fi (and horror, but more about that in a minute) is that well-worn themes get new life. Interstellar is one of the best examples of this. It’s about being a parent/providing for a shared future. But through the magic of relativity and the terror of monoculture farming/global climate change, we are forced to look more closely and from a different angle. So what are some other terrors/inventions that we have laying around that we might use?
