How conventional is the narrative of This Is England?

As this movie is intended to be over the protagonist (Shaun)'s summer holidays, the narrative must be progressing quickly but in a subtle way to not draw attention to that fact. In terms of time and space the feature does not include that many sets. The majority of the film takes place indoors, with more car scenes than the average film. This reduction in sets leads to a distraction from the progression of the narrative as the amount of conversations are disguised in the casual sets we are familiar with. This is due to the narrative revolving around Shaun, the 12 year old protagonist who features in all but one scene of this film. As he is a 12 year old he is much more constricted in terms of how far he travels from his house, in terms of realism therefore, the sets must be reused as he is in the same neighbourhood for 6 weeks.
We become aware of time passing as Shaun himself changes. The scene in which he becomes a skinhead progresses the movie onto a new sense of time in the film, when Shaun joins Combo's tirade we progress with him into the next stage of the film, when Shaun is alone on the beach in the final scene we can consider that as the end of his 'coming of age'. The final scene is also symbolised by the discarding of his St. George of England flag, we consider him to have completed his journey as he throws it into the sea.
the structure of this movie is unusual in that if we apply Todorov's theory to it, it will fit however there is two disruptions in the plot which could be considered as creating a parallel narrative. The first disruption is when Shaun first meets Woody, there is an equilibrium however Shaun is unhappy in it. Once being accepted by the gang we could consider that to be a new equilibrium, the protagonist is happy and no problems have been made. The second disruption comes following the introduction of Combo. He offers a choice to join him or leave him on his national front movement. Shaun accepts and the second disruption is completed. The new equilibrium is made when Shaun turns his back on the national front and possibly his nation as a whole by throwing away his St. George of England flag that Combo gave him.
In terms of character development there is a distinctive amount of well developed and rounded characters in this film. Although they have a relatively small screen time in comparison to Shaun, the characters are mostly three dimensional people. Their development is rapid, Combo for example is developed surprisingly fast as he joins exactly half way through the film following his release from prison. His speech sets out his views and his personality in one fell swoop. The development from Shaun is more conventional, his character arc begins with him being a lonely schoolboy who misses his recently deceased father and develops into him making his own decision in the rejection of the national front and everything it represents. This is conventional in that it represents most coming of age films as they show the independence of the protagonist.
