Completed it last night, a typical golden age of J dorama. Beautiful actresses, ugly actors. The plot over the top. I hate the main score like some wolf crying out of tune. So 7/10 for that.
It doesn't pitch itself as a horror drama, more like a sting of gory like Saw in that era. There is a surreal part which audience will question whether it is a reality or wish-it-were. A Miike's trademark of his visceral pain drama. 8.4/10
