If you were tuned into the film festival circuit in the early 2000s, you might remember the buzz. If you weren’t, you’ve likely seen its DNA in shows like Black Mirror or Mr. Robot . Two decades later, this low-budget, high-concept thriller about a world where citizens are ranked by a single numerical “authenticity score” is not only watchable—it’s urgent.

The highest are celebrated—until one woman with a 99 confesses she secretly hates her children. The crowd cheers louder. That’s real, they say. That’s authentic. A score of 100 means you are a
But the true legacy of IOI isn’t its plot—it’s its question. In 2003, Sofia Lin asked: If you could see everyone’s true identity score, would you look?
