Review of Gangsta.

I finished the last episode just a few minutes ago and i'm dissapointed because i have so many questions. I think there must be a second season for this questions but maybe it cancelled i don't know. In Gangsta, there is so much violance, sexual scenes, unreasonable flashbacks. In storyline, there is so much material but maybe 12 episode is not enough for explain it. The story has three main characters, Nicolas and Worick had an old friendship/master-slave relationship, they came to this city and there is Alex the woman who appeared from their window. Alex is prostitute, Worick is gigolo. It's seinen but wejust saw unreasonable nudity, every character had a good physic and obviously no clothes. We saw their past sometimes but it's hard to understand what happened and when happened. There is so much blank area so i don't like it.
