The target audience is mainly aimed at young males as the opening sequence as it is very masculine and females would not seem to be very attracted towards it, as all the characters male and the only times females are used are as victims or as in a sexist way. The masculinity of it all makes it more targeted towards the young males as it follows the characteristics of the male target film as there are hard hitting special affects, such as large explosions and conventions such as drugs and a stock character of a confident working age male with a cockney accent which appeals to the males as they wish to relate to these.
The narrative is organised and structured in the way it has as it is giving the introduction first so that there is basic background knowledge to know what is going to be expected further into the film, but enigmatic enough not to give it away, such as in the opening sequence it is giving them a brief history about him and drugs progessing through the years and different social cultures and then the end of the opening sequence it ends with him giving himself a brief introduction so nothing is given away. The audience is positioned as they are being told something which they are oblivious to know what is goign on in the underworld of gangs, so the opening is basic enough for them to understand, however it is keeping to the conventions of gangster. So they are leaving sterotypical gangster attitudes there which the audience will understand. Tension is created from the large explosion from the start which is a major impact, the way it is maintained is the constant movement of the camera and the upbeat music, the camera does not once stop for one second so there is a flow.
