Research and Planning - Target Audience Top 40

The target audience age for my horror movie is going to be between 18 and 21, the typical student age, so I conducted some research into that age categories favourite movies of all time (as shown below):

The horror genre doesn't seem to feature very strongly at all within the top 40 films my target audience most likes. However, by ratio, there have been less horror movies in the cinemas over the years in comparison to fantasy and action films, which feature more prominently in the top 40 list above, making this list slightly unfair on films of the horror genre.
