Human trafficking

There has been a trailer on Pearl channel, I didn't notice it at first, as I usually 'listen' to television instead of 'watching' it. What is said in the trailer gets my attention... forgot the exact wording but the idea is, 'drug, you can sell only once; but girls or women, you can sell day after day and over and over again'.
Search on the internet, here is the information of this 4-hour movie:

I'm not sure if I would want to watch this movie, it's not a documentary, does it serve to reveal the truth and raise awareness? or is it just making use of misery to entertain?
