Why is horror scary to some people and why do other people love it?

             "Some people may like scary movies because they enjoy the adrenaline rush of being scared while being safe, Cantor said. “Some people like anything that gets their minds off their own problems,” she said. Individuals who are highly empathetic may not like scary movies, she said." (PsychCentral)

So some like the adrenaline rush, and others may not.

As a person who likes horror movies, I say it's probably because we know it's fake, like the make-up and costumes and the other stuff. We don't get scared easily because it's all fake, some people who don't enjoy scary movies could be highly empathetic can be overstimulated by what they see.

I don't know if that's the reason so sorry if you don't get it.

answer; i believe the correct answer is (forms with no projecting parts that could break;

lines and shapes are a part of the visual elements which can be played with and used to create a mood or feeling in a composition.

some of the other elements include the pattern, color, tone and texture. all these elements serve together as the construction blocks which are used by the artists to create artwork.

lines are used to form drawings and different shapes are formed when these lines are used in certain lengths or angles. so the artist can play with these elements of art to create and express different moods, thus conveying different  meanings.
