Research- Horror posters

For my horror poster research I chose to ask three individuals from my chosen target age range to analyse a variety of three different horror poster. My research was conducted through the social messaging app, WhatsApp, as a unique way to create a virtual focus group .My reasoning's for doing this research is to conduct a thorough analysis on what my audience expects from a horror film poster, with this understanding I will be able to add my knowledge of these expectations to my group and we then can create a product which is both effective and unique. On the right are the horror films, that I will be showing my target audience.
So what questions would be asked:
-What attracts you first and why
-What do you think is the scariest element of that poster/attraction
-What poster attracts you least and why?
