Cure
Cure is an incredibly unsettling film. The slow pacing and minimal explanations make the mystery feel even more disturbing, and the tension builds in a way that makes it hard to look away. The psychological element gives the film a deeper impact than a typical thriller or horror film.
Overall, Cure feels perfectly executed. It stays with you long after it ends, and I already want to watch it again to pick up on even more details. A truly outstanding film.
