"Under Paris" on Netflix is like 25% "Jaws," 15% eco-terrorism drama, and finally, in the last third of the movie, 782% "Sharknado: The 4th Awakens" - but, y'know, set in Paris. Cheer on the hundreds of catacomb-dwelling hyperintelligent flying supersharks (not making that up) who, for unexplained reasons, dislike the French (who aren't shown in the smartest light here).
Characters enter the script only to serve as future shark food before the movie's ending (which, oddly, doesn't exactly end). Any grasp of reality is tossed aside in favor of crazy spectacle. At one point a local explosion sets off a massive chain-reaction of gigantic blasts down the Seine that obliterate major bridges, trigger a tsunami, and entirely flood all of Paris with a dozen feet of water (despite the city being 115 feet above sea level AND more than 100 miles inland from the nearest ocean coastline). It's all just a final excuse to allow hundreds of supersharks unrestricted access to the French.
There has to be an "Under Paris" drinking game online somewhere, like "take a sip of Bordeaux each time a character enters shark-infested waters" or "drink when Berenice Bejo stares in horror directly into the camera."
Kudos to Yannick Dahan, Xavier Gens, Maud Heywang, and Yaël Langmannfor for completely bonkers script writing. Five stars.
