That's a good point, though I was thinking more of a psychopathic killer at the time rather than a war zone. I'm opposed to pointless gore, just for the sake of shocking. I guess that means my response doesn't really answer Duracell's question adequately.
One of the things that I disagree with most as regards onscreen sex and gore is that it is not treating the human person with respect, but objectifying them or making them an object of entertainment/shock value.
In Saving Private Ryan (which I need to finish watching some time--I started it at a friend's house and never finished), the gore is not shown just for shock value. It shows the horror of war rather than glorifying violence and making it look fun and exciting like most war shows do. I don't think that former portrayal is a bad thing. Thus, it isn't being disrespectful to the human person as a really gory horror show might.
