Over all it was great.
ZeroZeroZero overall was great. The action was great, the story telling technique was well done and the story is pretty bleak.
First and foremost the lighting of the show was really dark. At lot of it is hard to see. There are some parts of the story that I found muddled.
It is unclear to me what Stefano La Piana's scam was. He clearly wanted to take out his grandfather for killing his father, but I don't really understand how sabotaging the drug shipment would do it.
