Irezumi

A woman is kidnapped and drugged, then covered in a huge spider tattoo that may or may not have taken over her soul and turned her into a killer. She gets revenge on those that wronged her by becoming a geisha and causing their deaths.

A slow moving revenge movie centred around a geisha using her charms to manipulate men and killing them off. It's not really that much of a horror movie as the supernatural side isn't played up, even though it's hinted at. It's more of a samurai movie that happens to focus on the geisha and brief outbursts of violence that take the lives of others. It's interesting but not an amazing movie or anything.
