I came across this film without knowing much about it. It was listed as a thriller/horror movie, but yet made in Japan. So I gave it a shot and it was rather good.
The plot can leave you guessing in a good way. You might think Kasumi is the killer or maybe Asuka. Hell, even the retired police chief seemed like a suspect for quite a while during the film. And that is what kept it interesting.
The ending was not quite as I expected, but it wasn't bad. I was hoping for an even more twisted ending than what the writers chose. But them again, they had to explain the family connection of Kasumi. And if the ending didn't involve the family somehow, then it would have wasted a lot of time for nothing.
Overall, its a good film. I am not your biggest thriller fan, but this was good. Japanese or not, its worth a look by anybody. "B"
