Readable/watchable dialogue is the backbone of every story. If the reader/audience member is not engaged by the dialogue, it is highly unlikely that they will finish reading the book or watching the movie.
In 2014, writer James Scott Bell published How to Write Dazzling Dialogue: The Fastest Way to Improve Any Manuscript. Breaking down writing dialogue into the nuts and bolts of writing, Mr. Bell shows how good dialogue engages and invites the reader/audience member to continue with the book/movie while bad dialogue throws the reader/audience member off and makes them question if they want to finish reading the book or watching the movie.
What I liked about the book is that Mr. Bell plainly lays out what good dialogue looks and sounds like vs. what bad dialogue looks and sounds like. He also recommends exercises that are designed to stretch a writer’s technical muscles and teach the writer how to write engaging dialogue.
Do I recommend it? Yes.
