Shin yôjo densetsu: seirên

"Is that you? The female ogre who sings a song?"

Siren is a sleazy, low-budget Japanese flick about a group of criminals that fall under the deadly influence of a mythological siren. At least, a version of a siren that is invulnerable to bullets, can sing with its mouth closed, likes to lick its lips a lot, and looks just like a busty young Japanese chick.

After successfully robbing a bank, five men kidnap a beautiful woman that happens along their path and take her to their hideout as part of their "celebration". But the woman is actually a supernatural creature that can kill with her voice, and she uses her beautiful exterior to alienate the greedy men and turn them against each other to bring about their deaths. Why does she have to have sex with the men before she kills them? Don't ask me. 

I'll be honest, there's not a lot of reasons to recommend this, even though it's not exactly awful. If you just want to ogle Sola Aoi, there are much more..."rewarding" sources available. The story is bare-bones (imagine a pedestrian, unimaginative riff on Reservoir Dogs with the addition of a hot manipulative woman who takes her clothes off every few minutes) and the acting is mediocre, even by the standards of this kind of movie. The short running time MIGHT make it worth checking out if you still find yourself overwhelmingly interested. Siren just barely sneaks across the line into "watchable" territory.
