“Superdeep” attempts to blend elements of cosmic horror, claustrophobia, and body horror, reminiscent of films like The Thing (1982) and Event Horizon (1997). The atmosphere is eerie and oppressive, with dimly lit industrial corridors and grotesque biological mutations.

While the concept is intriguing, the film struggles with pacing and character depth. Anna, played by Milena Radulovic, is a strong lead, but the supporting cast often feels forgettable. The film spends much of its runtime on buildup, and though it teases high-stakes horror, much of the action occurs off-screen, leaving some viewers unsatisfied.

One of Superdeep’s strongest aspects is its practical effects, which deliver disturbing and unsettling visuals. However, some CGI elements feel unpolished, occasionally breaking immersion. Additionally, the story becomes muddled in the second half, leading to a somewhat confusing climax.

Despite these flaws, Superdeep offers a unique take on the underground horror subgenre. Fans of slow-burning, atmospheric horror with a focus on infection and transformation will find something to appreciate, though it may not reach its full potential as a gripping sci-fi horror masterpiece​.
