Long-take digital cinema about people stuck in an endless videogame maze of subway tunnels. Not since A Quiet Place has a movie spelled out its rules this clearly on signage, and not since Cube has the puzzle been solved by a late-arriving autistic guy (a kid, in this case).

When a body meet a body passing through the tile. I picked the poster behind them as anomaly, but Escher’s first name really was Maurits:

You have to go through the loop correctly (turn back if you see anomaly, proceed if not) eight times in a row. We switch perspectives from Guy 1 to Kid to Guy 2. Each guy has parental anxiety and they keep stopping to get emotional or else the movie would be shorter. I liked the loop concept more than the psychological details. One run is all anomalies, peaking in an Atonement tunnel flood.
