I liked this movie! It's very dark in how it show us the world of today, don't get your hopes up. You are left on your own and nobody is going to help you.
The story is not that special and does not really leave an imprint, but the pictures and the mood make it a nice view. The gloom and the feeling of being unable to make a difference kind of get to you.
It have the basics for it's genre: rape (repeatedly), torture, violence, nudity (but censored - kind of funny here in the western world where some nudity is OK, but the violence showed in this movie would make our censors go nuts), help from people you don't expect. Downright Evil bosses of some strange trafficking organization. Drug abuse, Malplaced showering scenes. Evil for it's own sake.
This is not a movie that I'm gonna see over and over again but I would recommend it to my friends (but not to my parents).
If you like the genre this is slightly more than one hour well spent.
It have a nice twist at the end and does not finish like you expect.
