A little true story about how scary a horror game is

To say that a horror game is scary or not, is like eating hot pot in slightly spicy or medium spicy. I think that among the people I know, I am good at spicy, but there is a good brother in Jiangxi, who claims that he can't eat spicy, but when we eating rice noodles（Jiangxi specialty）, I saw the difference between those who can really eat spicy and my definition of the three words that can eat spicy.
Going back to the game "Back", to be honest, as a heavy horror game player myself (offline horror rooms are the kind of one person to enter), I also feel it's not scary. In the process of communicating with the director and the actors, I kept saying "no horror, no horror." However, to tell a true story is that the little sister who is responsible for editing the film crew, when editing the clip, does not pull a few people with her, and does not dare to cut it alone. (This is true), even the other Northeast brother, can't even play. So I asked myself, my own horror movie now, take the famous "The Grudge" for example, in my horror rating is what? If divided into: micro fear, medium fear, heavy fear. “The Grudge” only be micro fear. So, scary or not scary, it's really embarrassing. If a brother doesn't think it's scary, just look at it as a slight fear. Can only say, for the heavy fear of players, there may be some disappointment. But if we can really film that level, on the one hand, it is not our budget can handle, Hire James Wan?（Out of budget） On the other hand, really at that level, how many people can accept it?
Hope to be able to align with everyone's understanding of "horror ". No right or wrong, just discussion.
