Hello,
I noted down a few errors. Hope it helps!
In the movie "Why We Crave Horror Movies," author Stephan King tells usabout why we love violence so much and how we are a little bit insane
Another reason thatwhy I also agree with [What do you agree with?] is that we want to test our fears.
The last reason why I agree with Stephan King is, "we go to have fun" (2).
I really like your conclusion. You really put your personal thoughts into it, which is great. However, you can further strengthen your essay by using more concrete, real life examples. The elaboration of your points is usually very vague and is made up of some hypotheses, for example,
For instance, we go to see horror movies to prove that we are not afraid or maybe we go to see horror movies because we fantasize doing something like that in the real world
which can easily be deemed as assumptions by strict markers. So read up on the subject, and your essay will become more powerful. All the best!
