A simple list of five things I want to avoid in my stories.
1) The Mary/Gary Sue Protagonist
The character who is always right and always wins. Every likes her. No one can defeat her. She never does anything but always comes out on top.
2) The Cartoon Antagonist
He’s evil because he is. No depth. No personality beyond opposing the Protagonist. You can’t really hate him, because there isn’t enough of him to hate.
3) Consequence Free World
Buildings are destroyed, vehicles crash, banks robbed, people hurt or killed, but in the end everything turns out okay. Sometimes with music.
4) Static Characters
The character wakes up, goes on an adventure, experiences pain, fear, joy, and victory, and wakes up the next day the same character.
5) Repetitive Challenges
The Antagonist only interacts with the Protagonist in one or two different ways. No real variation in their stories, and the Protagonist is never really challenged to grow.
