I agree, it's only appealing to our basest urges. Most of us don't get much violence in our normal lives so it's removed from the mundane and therefore somewhat interesting. It's amazing how much violence we witness on TV/movies when there is really so little in our actual lives.

I get bored with the "neater world where the good guys are good, and vanquish the bad guys" stories, but there are still lots of interesting stories out there.

I don't even watch the nightly news for the same reason, it's all rapes and stabbings which I could have done nothing to prevent. I am constantly thinking to myself, "why do I need to hear this?"
