Very interesting post, you can sense your enthusiasm throughout. I'm quite glad there wasn't a philosophical, socially conscious side to this, like "why do we want to see people being killed in movies?" - It was nice to just think about the art of making deaths realistic in film!
Though sadly I do actually think we are being further desensitised to killing and blood and gore through games and movies, and more recently even music has become an avenue for violence. We are a bloodthirsty generation!
