Narrative Structure/Theory

In order to ensure that I have an engaging narrative I have examined the narrative structure of my film and theories it could relate to.
I have a fragmented narrative in my film with time shifts. For example I open the film at the end of the night before going back to the beginning as this creates enigma and will hopefully make the audience want to know what happens which is essentially Bathes' enigma code.
I have also thought about Barthes' cultural code which is a narrative device that the audience can recognise as being part of a culture as I have chosen to portray a stereotypical teen party culture/scenario which should be engaging to teenagers and young people who are my target audience.
My film could also be seen to contain set character roles which is a narrative theory proposed by Vladimir Propp. However my character roles differ from the ones he proposes as my film does not follow a traditional fairytale narrative which he based his theory on but instead portray set character roles of comedy horror films.
My narrative differs slightly from Tzvetan Todorovs narrative theory which states that narratives often start in a state of equilibrium that is then disrupted before normal life or a new equilibrium resumes as my film starts in a state of disequilibrium then goes back to the original state, develops into disequilibrium before returning to normal. The overall plot of the piece fits the theory completely but the portrayal of it to the audience differs slightly.  This will hopefully leave the viewer feeling a sense of satisfaction as all the enigma in the film is resolved by the end of it and should leave them happy at the end of it.
