Writing good dialogue is a craft few can master. Lewis Criswell draws from a nice survey of recent and classic examples, both good and bad, to explain the craft of designing dialogue.
Dialogue has the potential to do more than just further the plot, he argues.
"A sign of imbalanced writing is a script saturated with expository dialogue… Too many question marks on a page is a good indicator something has gone wrong."
