This is a movie that famed director Kiyoshi Kurosawa made by demand for a TV company, after the success of Ringu. Well, there's a kind of Sadako feeling to it, the girls looks a lot like the one in Hideo Nakata's Dark water... but this is a flawed movie. Terrible script. Not scary at all (and I scare so easy! that's why I love terror movies). Forgettable.
For instance (spoiler coming) at the very beginning of it, the psychological expert tells us about how, when a person sees her or his doppelganger, double, it's an omen of death. And then, one of the main characters actually goes through this experience... and doesn't die! Why sow a seed if you ain't going to follow it to the very consequences? I really don't get what's all the fuss about this guy... I love Japanese movies, I study Japanese, so if I find a Japanese movie too boring, I just listen... but I think this guy is overrated.
