It won't be easy to find a theater showing this new J-horror classic from director Kiyoshi Kurosawa (no relation to the great Akira). But it's worth dropping whatever you're doing to t the search. While crap like The Fog litters the multiplex, Kurosawa has to fight the amateurs for attention. Set in a sterile office building in Tokyo, the film concerns a computer virus and a rash of suicides. And that's all I'll say. Just know that Pulse possesses the dark art to make your pulse pound and your hair stand on end — with no cheating.
