Saw a snippet of "Scariest Horror Films" or some such show a few months ago...one of the top 10 was a Japanese (or maybe other Asian area) flick, and now I am trying to recall the name.
The plot was about a young woman who'd been rejected by others (men, jobs, etc.) and finally snapped by taking them back to her place and using all kind of evil devices to extract revenge. I seem to recall needles played a key role.

The reporters/commentators all said the same thing: Scary as Hell. and almost unwatchable. Yeah baby!
So, horror-film guys, what's the name of this "pointed" flick?
