I like horror as a genre but I hate most horror movies. I don't care for cheap jump scares, or gore, or gross outs, etc. I feel like horror as a genre is best when it's psychological and plays on existential fears, fear of the unknown, cosmic horror. I like John Carpenter's The Thing because you are isolated in an arctic research station and you don't know who the thing is, it can mimic anyone, you don't know who to trust. I like Attack on Titan because (initially) the audience and the characters don't know anything, they don't know why the titans eat people, they don't know why they are stuck behind the walls, it is just their reality. I like Memento even though it's not considered part of the horror genre, I just found the concept of having anterograde amnesia and people taking advantage of you because of it scary.

We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age"
