“Dark Nuns” unfolds as a deliberately paced horror film centered on demonic elements. A strength of the movie lies in portraying characters facing seemingly impossible challenges. This isn’t a typical case of possession; instead, it involves a high-ranking demon—a general of Satan himself. The film effectively conveys the danger and fear associated with this ancient and malevolent entity through its words, actions toward others, and control over surroundings. It's clear that this is not something to be taken lightly. The idea of two nuns performing an exorcism on such a formidable supernatural force, rather than a priest, feels fresh. This element is presented in a darkly theatrical way, almost like a familial dynamic. However, the film suffers from its excessive runtime, which includes extended tangents and secondary storylines that don’t advance the plot. These diversions diminish the impact of what's most important to the narrative. Ultimately, "Dark Nuns" might have been more effective if it had remained more faithful to its central storyline and avoided unnecessary deviations. It’s worth watching, though perhaps not quite as good as it could be.
