Between what is presented and how is presented : historical re-enactment through popular culture

The abundance of the references to the past in the present causes some theoretical problems. In other words, usually analysing different manifestations of the past in e.g. computers games, Hollywood films and so on to much attention is paid only on content (what is presented). Formal aspects of each film, computer game and so on are omitted. I want to explore this problem a little bit in this short text by taking as an example a historical re-enactment movement of the Viking Age
