"Rosario" is a horror film that attempts to weave a complex narrative around family secrets, dark rituals, and supernatural occurrences. The movie follows the story of Rosario Fuentes, a Wall Street stockbroker who returns to her grandmother's apartment after her sudden death, only to discover a hidden chamber filled with occult artifacts. As Rosario delves deeper into the mysteries of her family's past, she must confront the buried secrets and face the truth about the sacrifices and choices they made. With a runtime of just 88 minutes, the film tries to pack a lot into a short space, but the end result is a mixed bag that fails to fully deliver on its promising premise.

The film's strongest aspect is its atmospheric tension, which is expertly crafted through a combination of creepy sound design, eerie visuals, and a haunting score. The hidden chamber, filled with occult artifacts, is a masterclass in building tension and foreboding, and the supernatural occurrences that plague Rosario are effectively unsettling. However, the film's pacing is often rushed, with key plot points feeling glossed over or convenient. The characters, aside from Rosario, are woefully underdeveloped, making it difficult to become invested in their fate. The film's themes of family secrets and dark legacies are intriguing, but they are not fully explored, leaving the viewer with more questions than answers.

Despite its flaws, "Rosario" shows glimpses of a more nuanced and thought-provoking film. The movie's exploration of the sacrifices and choices made by Rosario's family is a compelling one, and the film's use of occult rituals and supernatural occurrences adds a layer of depth to the narrative. However, the film's failure to fully develop its characters and plot points holds it back from reaching its full potential. With a TMDB rating of 5.8/10, it's clear that "Rosario" has divided audiences, and it's easy to see why. While the film has its moments of tension and unease, it ultimately feels like a missed opportunity to explore the darker aspects of family legacy and the consequences of playing with forces beyond human control. Overall, "Rosario" is a horror film that is worth watching for fans of the genre, but it may not offer anything new or particularly memorable for viewers looking for a more substantial cinematic experience.
