What could have been just another RING rip-off turns out to be one of the most thought-provoking and genuinely eerie films I've seen come out of Japan: it's a film in which the door between the living and the dead is accidentally opened, leading to all manner of sinister events as it transpires that the dead are returning to Earth.
Like most J-horrors of the past decade, PULSE is a slow burner that moves almost glacially, gradually slotting in the various pictures of the jigsaw as its final game plan becomes apparent. Saying too much would spoil the intriguing, dream-like narrative, suffice to say that this is a film that doesn't disappoint at any stage during its progress. The 'ghost' segments are supremely creepy and disturbing, countered neatly by shock suicide scenes and a clever bit of FX involving a plane that was later cribbed for Alex Proyas's Hollywood movie KNOWING.
The cast give typically understated performances that increase in intensity as the character list is gradually whittled down, leading to one heck of a grim climax. Altogether, I can't fault the direction, writing, acting as all three combine to deliver an imaginative and thoughtful ghost story that's extremely different from most of what's come before.
