Key opinion
This adaptation of the Keigo Higashino novel offers a deeply emotional and atmospheric exploration of love and sacrifice through a mathematical lens. While the film is praised for its intense character studies and performances, viewers are divided on whether its deliberate, contemplative pacing and focus on melodrama succeed or feel overly monotonous.
| Acting | Ryo Seung-beom delivers a captivating performance as the quiet, obsessive math genius whose logic drives the narrative. | |
| Production | The film excels in building a somber, rain-soaked atmosphere that mirrors the internal turmoil of its characters. | |
| Emotion | The emotional stakes are elevated by the protagonist's desperate, tragic commitment to protecting the woman he loves. | |
| Pacing | The contemplative, slow-burning pace and heavy use of flashbacks reward patient viewers but leave others feeling that the narrative lacks momentum. |
