We are a country of excess. So it's not the violence, per se, but the exacerbation and constant repetition.
I hate a movie that will end by telling you that the first thing you should do is learn to love yourself. That is so insulting and condescending, and so meaningless. My characters don't learn to love each other or themselves.
There is no great invention, from fire to flying, which has not been hailed as an insult to some god.
