It unfolds like a fairly classy suspense film about a rarely seen threat. It does not look cheap in the way Sharknado did, for instance. It’s quite competently shot and edited, it’s tense, and it’s frightening. In other words, it gets the job done.

A solid shark thriller whose admirable but clunky eco-warnings almost get in the way of a good time. Best when it allows itself to really go in-Seine.

One of the most substantive of the many aquatic-attack horror movies that have tried to coast along in the wake of Steven Spielberg’s Jaws… But when the inevitable bloodbath starts, Under Paris seems to be cribbing from much messier shark attack movies.

The impartiality of the film to details is actually the most astounding part of Under Paris.
