What is the importance of narrative/genre in creating meaning in the films you have studied

The narrative in both films i have studied are circular narratives as both begin at the end. City of God is stylised where as La Haine uses realist framework to set a certain tone. In La Haine circular narrative is used to highlight the on-going crime and the cycle of violence in French society by showing the beginning and ending in a similar way- with a murder and Hubert's repetition of "So far, so good, so far so good, so far so good." City of God uses it to showcase the ongoing problems in the favelas by using Lil Ze as a sort of Case study. The Runts show how there is a circle of violence as even though they are young, they can easily commit murder due to fact that they are desensitise to it.
La Haine adopts a continuous, linear narrative that follows the lives of three underclass men, 24 hours after riots. The narrative style helps portray to the audiences how boring underclass citizens lives can be as there is no jobs and the school was burned down. The use of the clock in-between scenes reinforces this point, however, it can also be seen as counting down to Vinzs death.
