The fact that it's based on a true story makes it interesting because it could be about real people's experiences with a swarm. Maybe it shows how they overcame difficulties related to the swarm, like a swarm of locusts destroying crops and how the farmers fought back. It could also show the scientific research behind understanding the swarm behavior if it's that type of story.
I'm not sure exactly. Maybe it's inspired by some real-life events or a combination of various fictional ideas. But the specific source is a mystery to me.
One key element is the cause of the swarming behavior. In a true - story - based swarm story, it could be due to environmental factors. For example, if it's an insect swarm, changes in temperature or food availability might be the trigger. This real - world cause adds authenticity to the story.
Most likely not. Usually, if a work is based on a true story, that's made clear. But in the case of 'Swarm', there's no indication that it's rooted in reality. It's likely a product of pure imagination and creative writing.
