I don’t typically judge films on whether they have a cheerful or depressing resolution; my focus is on the effect they create. If a movie resonates with you, if it stirs something within you, that suggests strength and accomplishment, regardless of whether that feeling is pleasant or unpleasant. According to my standards, this film earns a perfect score. It genuinely shook me up. I’ve watched numerous horror films over time, but this one had a profound impact because, unlike supernatural stories involving demons and similar entities, it feels grounded in reality—meaning the events depicted could potentially be occurring somewhere in the world. As viewers, we naturally empathize with characters, and I experienced considerable distress on their behalf while watching this film. It left me feeling intensely frustrated, and for hours afterward, as I lay in bed, those final moments replayed in my head, prompting me to consider how I would react if I were in their situation. I won’t reveal any plot details, but be advised that if you're easily upset and choose to watch it, prepare for a disturbing experience. It is exceptional work, though the ending is deeply sorrowful and upsetting.
