Researching into horror sub-genres

For my final product, I researched into the sub-genres of horror, I did this so I could get a greater idea on the different types of horror I could create and what conventions I would have to follow. The four sub-genres I focused on was Psychological, Slasher, Monster and Zombie. I created my research on the website 'Canva', it is a website designed especially for detailed mind maps, I would also need this research in order to create my own product as I now have the influence and the conventions I will need to follow when creating my film poster and trailer.
