Rating: ★★★★☆ (Four stars. Would lose half a star for the awkward sex scene involving a scanner, but honestly, it’s kind of brilliant.)

The film’s most haunting scene involves a "score reveal" party, where people project their numbers on their foreheads using smart glasses. The lowest scores are laughed out of the room. 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.

There are some films that feel like a time capsule, and there are others that feel like a prophecy. The 2003 independent drama The Index of Identity —often shortened to IOI by its cult following—somehow manages to be both.
