“Underwater” (2020), directed by William Eubank, is a science fiction horror film that immerses viewers in a tense, claustrophobic, and terrifying underwater environment. The film stars Kristen Stewart, Vincent Cassel, T.J. Miller, Jessica Henwick, John Gallagher Jr., and Mamoudou Athie, and it combines elements of survival thriller and monster horror genres to create a gripping experience.

The story follows a group of researchers and engineers working at a deep-sea drilling station, the Kepler 822, located at the bottom of the Mariana Trench. When a massive earthquake devastates the station, the survivors must navigate through the dark and treacherous ocean floor to reach safety. As they make their perilous journey, they discover that the earthquake has unleashed monstrous creatures that threaten their lives.

Kristen Stewart plays Norah Price, a mechanical engineer and the film’s protagonist. Stewart delivers a strong performance, portraying Norah as a resourceful and determined character who must confront her own fears while leading her team to safety. Her character is compelling, and her resilience and quick thinking drive much of the film’s tension and drama.

Vincent Cassel plays Captain Lucien, the experienced and calm leader of the crew. His character provides a stabilizing presence, and Cassel’s performance adds depth and gravity to the film. Jessica Henwick’s portrayal of Emily, a biologist who struggles with the trauma and fear of their situation, brings a relatable and human element to the story.

The film’s setting and atmosphere are among its greatest strengths. The underwater environment is depicted with a sense of realism and dread, emphasizing the isolation, darkness, and pressure of the deep ocean. The production design effectively creates a claustrophobic and oppressive atmosphere, with tight spaces, malfunctioning equipment, and the constant threat of the crushing depths.

“Underwater” excels in its visual and special effects, which bring the underwater world and its horrors to life. The design of the creatures is particularly noteworthy, blending elements of deep-sea life with a nightmarish quality that makes them both fascinating and terrifying. The film’s sound design and score enhance the sense of dread and urgency, using silence and ambient noises to heighten the tension.

Director William Eubank’s pacing keeps the film engaging and suspenseful. From the opening scene, the film maintains a high level of intensity, with the characters facing constant danger and uncertainty. The film’s structure, which largely unfolds in real-time, adds to the sense of urgency and immersion.

One of the film’s themes is the survival instinct and the human capacity to endure extreme conditions. The characters’ struggle against both the environmental hazards and the monstrous creatures forces them to confront their own limitations and fears. This theme is explored through Norah’s journey, as she evolves from a traumatized individual to a determined survivor.

While “Underwater” received mixed reviews from critics, it was praised for its atmosphere, tension, and Kristen Stewart’s performance. Some critics noted that the film’s plot and character development were somewhat predictable and conventional, but these elements were often overshadowed by the film’s effective suspense and visual storytelling.

Overall, “Underwater” is a solid entry in the science fiction horror genre. It offers a tense and immersive experience, with strong performances, impressive visual effects, and a compelling atmosphere. While it may not break new ground in terms of narrative, it effectively delivers a thrilling and terrifying journey into the unknown depths of the ocean. For fans of survival horror and creature features, “Underwater” provides a gripping and entertaining ride.
