One reason it's interesting is that we can see her thought process. As she reacts to the scary stories, we can observe how she interprets the different events and characters in the story. For instance, she might make predictions about what will happen next based on the clues in the story. And when her predictions are wrong, her reaction to that is also quite fascinating. Additionally, her body language throughout the reaction can be very expressive, which adds to the overall entertainment value of watching her react to scary stories.
One reason could be the unique cultural elements in Indonesian horror. Their superstitions and folklore add a distinct flavor. For example, the concept of spirits like 'leyak' can be really creepy. The snarled nature might imply a complex and convoluted plot that keeps you on edge, constantly guessing what will happen next.
Well, when reacting to two - sentence horror stories, the first thing that comes to my mind is the shock factor. These stories are so short yet they can send chills down your spine. For example, 'I woke up in the middle of the night. There was someone standing at the foot of my bed.' Just this simple description makes you imagine all sorts of creepy scenarios.
Some might get angry. They could be angry at the characters for making the wrong choices that led to the sad outcome, or angry at the situation in the story that seems unfair. For instance, if a character in the love story betrays the other for no good reason, the reader might feel anger towards that character.
