Just watched it and i though it was good. It's well produced so even though it's a well documented story, it's still enjoyable to watch.
As posters said, the best part is the law enforcement angle of the documentary. It's interesting to see about the strength and weakness of each cases. Having Giacalone on is also a big scoop.
The weakest part of the documentary is the mob men and woman they interviewed. They didn't bring anything interesting.
