Sometimes people yearn for "simpler" times and refer the past as a good time to have lived. But as this and other movies show, all time periods have their issues or their problems humans had to endure and to live with. This has a high criminality in the center of the story but also corruption, so it is tough to recognize good and bad sometimes.
Yes gray areas are common and it is not a bad thing to show them. Especially when you show something (even in a heightened film form) that happened. The movie does feel like one of the US films that portrayed that particular time in history and you would be excused if you thought it was about that. Production design is really high and the actors are really good. And it doesn't shy away from violence either - not for the faint hearted and not easy to watch for sure - but very well made
