Dialogue: Abused and Misused by Joni M. Fisher
Savvy Authors Blog
People recognize terrible dialogue when they hear it in movies, or on television or read it in books. It comes off wooden, robotic, confusing, lecturing, boring or in some way artificial sounding. Examples abound in B-grade movies, comic books, soap operas, and probably in the last book you refused to continue reading. Don’t be that writer.
Dialogue is NOT conversation put on paper.
