How far can it be argued that your chosen films provide a 'realistic' representation of the people ad places they focus on?

City Of God

City of God provides an accurate and realistic representation of the people and places it focuses on. 

Over 7 million Brazilians now live in favelas, and the life expectancy of those involved in drug gangs rarely exceeds 20. Children as young as 10 are walking the streets, fully armed with military grade weapons and committing murders and other crimes.

This involvement in the drug gangs originates because of a dysfunctional family. In City of God, we see Rocket's brother Goose being told off by his Father in their bedroom just after the motel heist. The eye-level close up two shot shows the characters face to face, indicating conflict. However Rocket does not come from a dysfunctional family because he has a Mother, Father and Brother, so he has been raised with morals, as shown when he says 'I don't want to be a hood because I don't want to get shot'. This shows that Rocket is an exception - a break in the rules of society in the favelas.
