FOR GOOD OR BAD
Do books have morals? Maybe it's easier to ask "Do movies have morals?" I'm suggesting that words and pictures that appear for public consumption are not just entertainment, but they have an effect on us. And by extension, on our culture.
Writers are encouraged to grab the reader in the first sentence and keep them in suspense for the duration of a novel. That's one reason we see fiction take off with a sex scene and continue with murder, fist fights, and drugs for 300 pages.
Some thoughts on this in my blog for the Columbia II chapter of the SC Writers Association.
