Puh-leeze, Mr. Squeamish McAuthor, you obviously didn’t live through the late 70s - early 80s slasher film fad.
You have to look to foreigners for truly soul-destroying gore movies. You know, those “enlightened” Europeans? They can warp the brains of guys who watch Jason Voorhees marathons.
The French are really big into it, but if you want to question the existence of a Supreme Being and why He would allow mankind to create such horrible things, I’ve got three words: “A Serbian Film”. Never, EVER watch that movie.
Yup, they even twist up the holiday fare. Have a look at "Rare Exports: A Christmas Tale" sometime.
