How to make a movie on social aspects?

Rating: 10/10 (24 September 2015)

We often see movies on social issues, inequalities, crimes etc. Generally, the first rule crafted by most films is to pick a side. For whom should the support go to? Which side does the protagonist fight for? How well do they achieve "equality" in the end?
This is not most films. It's almost impossible to not take a stand while portraying a social issue. But that's where brilliance lies. This film taken a journalistic view on the subject. And it goes deep in it's research on why the protagonist picks his side in a visibly unequal society. We travel with the protagonist, what logic does he apply to his actions? Where did it all start for him? What took for his views to change?
And it isn't like a documentary.. it never gets boring. You walk into the lives of black gangs, white gangs, jews, mexicans.. each group with their own story to tell.
It's a film that requires an extraordinary performance for it to be subtle and convincing. And what better actor to portray it other than Edward norton. This guy can't act bad at all.. from being a hot blooded boy to an old wise man.
Incredible movie making and writing.
