How does your media product represent particular social groups?

I do not present social groups in general since film noir could also fall into the same territory as crime drama thus it mainly explored the relationship between the murder victim and the private investigator. The way I represented my character of my media piece was to have him as some sort of private investigator coming in to investigate the murder of a person found lying dead on the floor of an empty room. There is no dialogue in the film so that adds to the mystery surrounding the character as we don't know who he is, what he does and what his likes and dislikes are (an enigma). His appearance is that he is formally dressed and is clean and tidy figure as most private investigator-like characters are, his age could be somewhere in the late twenties to early forties range (even though the actor playing him is about eighteen) which again is the age range you normally associate with private investigators. His role in the narrative of the opening is to give us an idea of what happens in the plot of the film the opening is for (he's a 'bad memory' being lead into the 'erasion room' (the place bad memories are exterminated in)). In other words it's meant to show what happens inside the human head on a daily basis. It's debatable whether he is meant to be viewed sympathetically or unsympathetically since this is just the opening and his story of how he ended up in the 'erasion room' could be told in flashback if this movie was to have been made.
