The family—Tom (Andreas Pietschmann), his wife Julia (Émilie Duquenne), and their two kids—were enjoying a quiet boating trip when enormous objects began to plummet from the sky. Suddenly, the ocean had disappeared. Their boat was stranded on what appeared to be the seabed, now a dry, desert-like expanse, leaving everyone utterly confused. They managed to connect with another survivor, a diver whose diving bell was also stuck at the bottom of the sea. He explained something about the Earth’s poles switching and all the water rushing to the other side of the planet. The suggestion was to go join him, but first they ran into someone else who wasn't pleasant and quickly the family found themselves smaller in number, forced to walk and locate a radio contact before becoming prey for some creatures. It’s awful, and not just because it's completely unbelievable from beginning to end. The performances were among the worst I’ve witnessed, and while it’s a French film, that shouldn’t deter you—because there’s nothing in the script that improves the movie or creates any real sense of danger, which is largely missing throughout its ninety-minute length. What was most concerning was the ending, which implied another installment might be on the way. As my Paramount+ subscription nears its end, I'm starting to question if this is truly the best they can offer from a hundred years of filmmaking.
