A Kansas farm couple is trying to make a baby. The spoons start rattling, the earth moves — but not how you’d think — and the next thing you know they have a son on the brink of adolescence. One night his bed starts shaking — but not how you’d think — and the next thing you know he’s out in the barn scaring the chickens. Also hovering above the ground, speaking in tongues, and throwing vehicles and people through the air.

The boy’s name is Brandon Breyer. That’s his earthly name, anyway. On his home planet, they called him something else. Brandon’s resemblance to another young Kansan of extraterrestrial background, with an alliterative moniker and remarkable abilities, is surely no accident. “Brightburn” (the title refers to the Breyers’ hometown), is a superhero origin story reimagined as a horror movie. What if Clark Kent, instead of being grateful to the parents who raised him and a defender of truth, justice and the American way, had been a power-hungry sociopath whose motto was “take the world”?

It seems plausible. Skinny, smart and easily picked on at school, Brandon (Jackson A. Dunn) comes to believe that he’s not simply special, but “superior.” Finding less and less reason to play along with the pathetic human creatures who never understood him in the first place, he devises ever more elaborate and bloody ways of messing with them. The soundtrack hums with deep, tooth-rattling vibrations and the prairie sky is full of portents. It’s scary whenever you see the kid on screen, and even scarier when you don’t.
