When I'm my own editor, there's very little difference between the first draft and the final. I write what feels right to begin with. I rarely make any major changes.
You can read a dozen different textbooks or how-to manuals that will tell you the basic rules of what makes a story - a beginning, a middle, and an end.
It's all about who's where on the food chain. When I'm the story editor, I expect my writers to follow my vision. When I'm working for another editor, I'm obliged to follow their vision.
People who were more concerned with themselves and looking good to their readers then they were with the characters sacrificed a series for the sake of a story.
Sometimes you're not even sure which of your stories were failures. There are things I've written that I thought were complete catastrophes when I finished with them that have gone on to generate some of my most positive feedback.
The most unrealistic thing I've ever read in comics is when some group of characters calls themselves the Brotherhood of Evil or the Masters of Evil. I don't believe any character believes their goals to be truly evil.
