What an idiotic comment; especially the last line!
The psychological effects of prolonged exposure to extreme gratuitous violence in horror films (the sub-genre of torture/sadism/slasher) are well known. The effects are quite detrimental (particularly in youngsters/teens) and in many cases long-lasting. They include Persistent Anxiety, Fearfulness, Avoidance, Obsession, Desensitization towards Violence (especially towards Women), Lack of Empathy, Nightmares, Sleeplessness etc.
In my comment's defense, it at least didn't mistake an article from the Edina High School student newspaper for a scientific study conclusively demonstrating the effects of prolonged exposure to extreme gratuitous violence in horror films.
I purposefully chose the "Edina High School" article for you.
I might also add that the details there are from certified Psychologists/Teachers employed by the School (AP Psychology teacher Heidi Mathers and Edina High School psychologist Samantha Bialozynski). It is highly relevant since it talks about the effects on school students/teens who are the primary market for the horror film genre. These psychologists have more data and are in a better position to observe behavioural changes day-to-day than in outside studies.
I don't think you are capable of understanding more nuanced studies done by NIMH etc. However, i did give a well-respected and often-cited study by Kristen Harrison and Joanne Cantor in the other link. You are encouraged to read the original study (mentioned in the article) for edification.
