Arent they the same ?
Because what makes the human scared is the horror of the unknown…but a mystery?
Hmmmm….I guess on a mystery is considered a situation where it leaves a question mark…? But its not that scary but a question.
But I think for me Mysterious is an animation theme mostly used in detective animations.
And horror is just for pure scare to the audience.
I think mysterious is the most loved, because Studio Ghibli an animation studio which coincides in the mysteries of a fantasy world which people love.
