One can't be convinced that Wu Chien-lien, a woman with a body temperature of only 32 degrees Celsius, is actually a merciless assassin! How unfortunate that the filmmakers missed their chance of exploring the interesting implications of a person with a body temperature five degrees lower than everyone else and who only has a one-in-a-million chance of survival. Superficial as it is, the film is both alienating and romantic. Its most intriguing parts are the romance between Wu, the female assassin, and Lau, the noodle-seller, conducted in the tradition of a "midnight love affair with a beautiful ghost", and Wu's persistence in finding her roots.
