on Helping Writers become Authors:

We’ve all experienced it: a story that looks good on paper, features big-name characters, or starts with an intriguing premise—but somehow falls flat. Maybe the characters feel hollow, the plot drifts without purpose, or the ending lands with a thud. But what actually makes a story “bad”? Are there pitfalls you can look out for that can save your story? More importantly, how can you avoid these mistakes when writing or editing?
Bad storytelling is one of those things where you “know it when you see it.” Or, rather, you feel it. Sometimes when you read or watch something that isn’t working, it can be hard to put a finger on what’s gone wrong. And yet your gut knows. Your visceral reaction to the story may range from a mild sense of dissonance, confusion, or even boredom all the way up to outright irritation or even anger.
The good news is that, as writers, the moments when you start feeling the ick are the best teaching moments possible.
