Target audience research in depth

Researching the target audience of the Gothic Horror genre, and also gaining an insight into the different conventions, and even asking my focus groups on their opinion of certain parts of the genre, has influenced my trailer hugely.
In this video, I take a look into the different characteristics of the Gothic Horror audience, without generalising them as a whole, taking into account that some people may just want something new out of horror, rather than the standard slasher flick.
Upon looking at my target audience, and seeing the direct correlation between the love of Victorian literature, and love for the Gothic Horror genre, I decided to set my story and trailer in the late Victorian age. This is because I wanted my trailer to go with that convention of the genre, to attract the audience members that would be interested in history and Victorian literature.  I also decided to set it in this time period as very successful Gothic Horror films such as the " Woman In Black" were set in the late Victorian age, were scientific theory and rational thinking had taken over from the superstition that as displayed throughout the 18th century.
This to influenced my trailer, as I wanted my characters to have the rational, scientific mindset that was just developing in that time period, and have it challenged by the supernatural occurrences in the story. This is also a convention of the Gothic Horror genre, and is a very big plot point in ghost stories set in the Victorian age, as displayed also in the Woman In Black.
