A legendary German U-Boat lies at the bottom of the ocean, supposedly filled with gold, prompting a collection of submariners—far from an ideal team—to embark on a mission in an old submarine to change their fortunes. As you might expect, things don't go smoothly; there are secret motives, internal conflicts, and intense feelings of confinement. The question becomes: will anyone make it out alive? And more importantly, do you even care if they do? While *Black Sea* isn’t perfect, criticisms regarding its realism likely come from people unfamiliar with this kind of movie. Director Kevin Macdonald and writer Dennis Kelly have created a well-paced submarine story. The characters are familiar, clearly inspired by other films in the genre, but the relationships between them are tense, and the dangerous situations generate genuine suspense. *Black Sea* doesn’t revolutionize the submarine thriller; it simply keeps things moving forward. Solid performances and realistic visuals contribute to making this—aside from some questionable accents—a worthwhile experience. 6.5/10
