How does or film represent certain social groups in society?

I believe that our film relates more specifically to an adult couple between 20 and 40. I think this because of it's heavy "Who dunnit?"style and how it is filmed. Because of the build up to the point where the man is attacked there is a suspense that would be seen in something like a television audience. Where as the slight horror element to it can also help us appeal to the younger audiences of perhaps 18-25.
