There is no doubt that character development is nearly as important as plot development. Without a good plot, a reader or audience will never stay engaged, but what about our lead characters? One of the ways that I help to define a character, is to write a biography about him/her. It really does help to isolate response in any given situation. If you understand the history of your character, then it becomes easy to create believable responses within the storyline. In addition, while a storyline might be good, if the protagonist or antagonist are poorly developed and/or defined, it will have an impact on the story. A good developed character will leave the audience knowing the exact innate characteristics of the character and exactly how the character would react to a series of life experiences. Without good development, it will leave the audience confused, and disengaged.
