step father title seuqence

The structure of the opening 'Step father' gives an idea of what kind of movie it is, the narrative is shown clearly through the music and acting, as the story slowly builds we get the image that the man is changing identities immediately we wonder why he is needing to do this. The film then starts to create a more tense atmosphere as looking at the props in the background it slowly shows the tools used for the killing which is  accompanied by the sound of christmas carols in background and the sound of the phone of the hook. 

It then introduces a bigger story as we see a mother and her children lying on the floor - straight away we assume that they are dead which then gives sense that this is a phycological/horror thriller and the content of the story is revealed- we know that he his a murder.
