What is Horror about?

As research, my group and I looked deeper into some common questions related to the genre of horror. Firstly, we looked at synonyms for the word ‘fear’. All of the words we found are commonly related back to horror. We also brainstormed a few ideas about what we normally see in horror movies. After looking at many sites online, we came up with a few reasons for why people watch horror movies, and also looked at data to pick out the top four, best selling horror movies of all time.
