A worthwhile viewing experience that I'd happily watch again and suggest to others. It’s an excellent survival horror narrative that steadily increases the suspense as events unfold. The premise of being pursued within the subway system, surrounded by people experiencing homelessness and rodents, is something that really appealed to me. Unfortunately, as with many effective horror films, discussing specifics would involve revealing too much. I can mention that it features some strong ideas and a well-constructed plot, complete with unexpected turns and surprises. It's not exactly heartwarming entertainment, but that’s precisely what you’d expect from a survival horror story.
