Kiyoshi Kurosawas films have never been what one might call mainstream. However, Pulse no relation to the obscure electrical appliances amok film Pulse (1988) was the greatest success that Kurosawa has had to that point. Pulse was Kurosawas biggest box-office hit and also the film that made the greatest nods towards current commercial trends. In this case, Pulse was clearly inspired by the massive success of Ring (1998) with Kurosawa substituting haunted computer disks and internet sites in lieu of Rings haunted tv broadcasts and videotapes. The measure of Pulses success is surely that Hollywood ended up remaking it as Pulse (2006).
Kiyoshi Kurosawa creates an incredibly haunted atmosphere in the film. The stage is set perfectly during the eerie opening scene where Kumiko Aso enters Taguchis apartment and he greets and talks to her and then vanishes into the next room, before she follows him through only to find his body hanging. One of the most intensely haunted scenes in the entire film is where Haruhiko Kato enters the red-tape room and the mystery woman appears, moving across the floor towards him in a strangely stumbling, unnatural gait and then abruptly appears over the top of the couch as he hides underneath. Another equally fine scene is the one where Haruhiko Kato is trapped in the Forbidden Room at the end and the blurred-out figure of a ghost appears to him.
There are some dazzlingly original ideas to the film. The scenes where the character played by Koyuki explains the nature of ghosts as a metaphor for loneliness and says that there is no difference between those who are alone and those who are dead is truly striking. So too the scenes where she tells us that ghosts want people to stay alive rather than commit suicide because the afterlife is too overcrowded. It is here that Kiyoshi Kurosawa seems on the verge of conducting something uniquely new with the ghost story.
However, all of this has to vie with a high degree of frustration about the film. As is the usual case with his films, Kiyoshi Kurosawa gives us a plot that is so murky and impenetrable it is frequently hard to decipher what is going on. People do things like kill themselves for reasons that are never clear. There are a number of questions left unanswered at the end of the film. One could buy the notion of ghosts somehow entering the world, but what are the dead doing on the internet or trapped inside peoples photographs? What is the significance of the red tape that has to be placed around doorways? For some reason, the last ten minutes of the film turn into a social apocalypse with Haruhiko Kato and Kumiko Aso driving through a deserted city past burning vehicles and then a plane that comes crashing down into a building, while the wraparound fadeout gives the impression that the entire population of the world has vanished or become ghosts (exactly what is not particularly clear). Nevertheless, what Pulse does offer is a great deal of haunted atmosphere, which almost compensates for total confusion about what is happening.
