As a passage to the spirit world, technology videotape, cell phones, computer screens has lost its novelty. In this American remake of the spooky, more-atmospheric-than-coherent 2005 J-horror thriller, the ghosts blink and crackle into existence with an electromagnetic sputter, but really, they're not so different from the gauzy, see-through spirits of yesteryear. It would have been a lot scarier if Pulse's college kids, haunted by comrades who stare back at them from cyber-hell, looked like they had lives worth saving.
