Based on the 1st Episode. I don't really know what I expected when deciding to give it a try. I'm not into docu-dramas: I can't stand the interviews and the lots of "Oh so bad", "Oh so sad", "Oh so huge", "Oh so dangerous", etc...
I guess that if you're into this sort of things "a la REAL-TV" where everyone's (predictable) perspective (slowly) recounts the development of the episode's story, you may enjoy it. Especially if the topic tingles you.
But don't expect any high level analysis whatsoever: you'll get the depth the interviews will allow you to get. Furthermore, production value is very low: original footage, few (and as cheap as possible) reconstructions, interviews. Low standards boring television unless you're really interested in one of the stories (in which case you'll get just a sensationalistic introduction).
