To each his own, I think people are taking this way too seriously forgetting it's just a shark movie.
Me, I love a good stupid movie, I really do and when you couple that with some over the top shark shenanigans, you're usually in for a good time. For the most part I enjoyed Under Paris but I think the movie's biggest problem is it doesn't know whether it wants to be a serious study as to how negatively humanity has affected nature (the Siene river is one of the most polluted rivers in the world) or just a fun action movie a la The Meg. The first half of the movie wants so badly to be Jaws, you can almost hear the theme music playing every time Sophia has a flashback, but once they go into the catacombs and discover Lilith's nest, things veer into the realm of the ridiculous, admittedly the best aspects of the film.
