I am fortunate that my girls are not interested in seeing these types of movies, but if they were, they'd have a tough time selling me on the idea. I watched horror movies in my teens and wish I hadn't. Even though most of the horror movies of those days were pretty hokey and unrealistic, they still invited a spirit of fear and left graphic visual images I will never be able to erase.
If kids can show me a way that watching these movies will glorify God, I'll get on board. Until then, I will continue to discourage teens (and parents) from supporting an industry that has total disregard for the mental health of our children.
In case you don't feel like reading the whole article, here are few quotes:
"“To me, it’s aesthetic, not a question of society. There is nothing you can do wrong in a movie.” --Quentin Tarantino, when asked if the use of graphic violence in film is a good thing for society
"'Saw’ was a huge hit, proving that mainstream audiences have an appetite for sadism – at least if it's cleverly conceived." -- Time's Rebecca Winters Keegan
“[Musician/director Rob] Zombie says in his movies, violence is not gratuitous – it’s the point.” --NPR's Neda Ulaby
