In the end, the overarching message of "We Can Be Heroes" should resonate with audiences of all ages. Kids are the future, and they're smarter and more capable than their parents sometimes give them credit for. From the adults' perspective, the notion that children should have more of a say in the future because it'll be their world to run sooner rather than later is quite powerful.
In the real world, kids who are about the same age as the heroes in this film are facing an ever-changing planet that's going to become even more complex and difficult over time thanks to climate change, an onslaught of new technologies, social media, and so much more. As any grandparent who had their 10-year-old grandchild set up their wi-fi connection knows, kids are more acclimated to these changes than we might think. More importantly, they're also the ones who'll have to face the long-term consequences of all these changes, for better and for worse.
We find out in "We Can Be Heroes" that the alien invaders who'd promised to take over were actually just showing the kids their own power to make change. And in doing so, "We Can Be Heroes" lets the adults watching know that they might need to give a bit more credence to what their kids have to say about their own futures, as well as the world at large.
