Kiyoshi Kurosawa’s 2001 J-horror film Pulse (or Kairo, which translates to “Circuit”) operates on two levels: 1) on the atmospheric level, stemming from the film’s mis-en-scene and sound design, creating a fully distinct audiovisual world from pure “vibes,” and 2) as a traditional genre story, since it presents a baffling mystery involving two separate plots which will purportedly be unveiled over the course of its telling.
Pulse succeeds with the first of these, and fails with the other. Its achievements, however, while not enough to completely rescue the film from its (more or less) mid-tier quality, were enough to earn it the status of cult classic upon its release. There are a number of memorable scenes—including what may be, according to one reviewer, the signature sequence in all of J-horror—and an overall aura that believably captures the anxiety over what was fairly new technology at the time: the Internet, and all its attendant dangers, particularly that of mass social alienation.
Pulse is a ghost story, but calling it a ghost story would be to, in a way, undersell the film; at least in terms of its ultimate scope, which widens out from a tight-knit circle of friends in the Kantō region of Japan to eventually encompass the whole world. This enlargement is ambitious but also turns out to be Pulse’s weakness, as its eeriness is most effective when confined primarily to the situation of the main characters. Like many intriguing mysteries, the payoff turns out to be less compelling than the mystery itself. […]
