My two cents on gangster related stories. A lot of it depends on your ability to morally submerge yourself. When your mind goes to that universe, your own moral judgement ceases to apply and you accept the moral paradigm of the protagonist, and it just becomes a political adventure.
That's one way of relating to it, but it's not actually
my way of relating to it. I'm able to use my sense of empathy to understand how the Mafioso character perceives the situation, and I'm able to be invested in the stakes of the entire conflict,
without morally submerging myself. If I'm watching
The Godfather or
Scarface, I might be fascinated by the characters and their conflicts, but I never lose sight of my the fact that these people are murderers who ought to be made to pay for the harm they've inflicted on others. The same principle applies to, for instance, political thrillers or historical dramas.
(Indeed, this speaks to one of the recurring themes of the gangster genre: That the state is just another mafia.)
But, that's just my way of relating to gangster films. Full temporary submersion is also a legitimate way of relating to the work.
Mob movies that focus on civilians getting wrapped up in crime like Ozark serve to distill moral decisions to their most simplistic. I’m faced with certain death for my family if I don’t do these horrible things, to satisfy these violent killers I ended up working for, how far am I willing to go?
One of the reasons I think the base ideas often end up being the best is that they’re the least constrained by real world limitations. Your cool idea can’t break realism because there’s no realism to break. Whereas a period piece or political drama has to accurately reflect how humans actually behaved in a place and time.
I mean, yes and no? I think it's really important to bear in mind that a lot of gangster stories are based on real-world personalities and conflicts from the history of organized crime. So sometimes, they
are working within the constraints of the real world -- it's just that real life has fewer constraints than we like to imagine in our day-to-day lives. So I would say it's not a matter of not being constrained by
real-world limitations, but of not being constrained by
conventional social limitations.
I would go one step further and say that one of the dramatic strengths of the gangster genre is that the stakes are very clear, very high, and very easy to relate to emotionally. If
The Godfather's conflict between Mafia families fighting over the control of the drug trade were to be translated into a more common real-world experience, it would be about two corporations competing with each other for product sales; the stakes may be high for the characters ("I want my bonus! We need to placate our stock owners!") but they would not be easy for the audience to relate to. But if you present the basic conflict of
The Godfather -- one association of people competing with another association of people for product sales -- in the form of the gangster genre, the stakes become life and death, because the constraints of a conventional life are removed. Same thing if you, say, translate the conflict into the science fiction space opera genre.
