KAIRO

Kairo (a.k.a Pulse) is a 2001 Japanese horror film written, produced, and directed by Kiyoshi Kurosawa, and starring Kôji Yakusho, Kumiko Asô, Koyuki, and Kurume Arisaka.

The movie's plot focuses on the isolation that Japanese people are experiencing due to the Internet invading the world and the loneliness this provokes.
Many strange things start happening in Tokyo; after one of their friends die, a group of friends start looking for the possible reasons for his apparent suicide. Visions of dead people, shadows on the wall, and even online suicides is what they find along their way. It appears to them that people are trying to communicate from beyond after living a life of oblivion and self alienation due to the constant use of the Internet and the lack of social life.
The film is developed in two different story lines whose protagonists meet at the end for a last attempt of survival from such apocalyptic set of events.

In this, somehow slow paced movie, director Kurosawa masters to create a dark atmosphere of surreal but yet plausible events in an apocalyptic time. We get the idea of a quasi-painful reality: we, humans, are bound to live alone and death is just the beginning for a longer and unavoidable loneliness.

This movie ends with no happy ending and no apparent future for its survivals; solitude seems to be our reality in the present and it will be in the future to come.
