Query: WOW!

Normally I don't watch documentaries, but I was sent this one as a screener and it was terrific ! ! It was a winner at this years Sundance Film Festival and features some of the best most honest interesting interviews I have ever seen. It manages to show all sides to the business of kidnapping in Brazil, from victim to perpetrator, to police & prosecutors to the corrupt judicial officials who refuse to convict government officials who break the law of the land.Well worth the purchase price and the investment of time to watch.
