I won't see this film for the same reason I didn't see Passion of the Christ... I don't need a movie to tell me how bad this is/was. If you've been to South America, you know why this is possible. The contrasting poverty creates desperation or disparagement. Opportunists abound to take advantage of that. It's horrible. You could say the same for much of the Middle East and Africa. The presence of tribal systems seem to add to the perceived legitimacy of much of what's going on.
In the US, it is trafficking laws that are turning out to be the most effective against prostitution rings. It really provided leverage to go after those running the prostitutes instead of being relegated to arresting only the prostitutes themselves. The fact that these laws/policies are needed at all is another thing.
