Like any writer, you skip directly to the comments. After realizing that the reader completely failed to appreciate how your script was trying to reinterpret the Really Big Bug Attacking Cincinnati genre, you look over the document again. What you need to understand, fellow writers, is that coverage has nothing to do with the art of moviemaking. Art is what you do at your desk at home, writing the script, honing your craft. Art is what directors do on the set with actors, what makeup artists do bright and early each morning, and what the FX guys do after shooting is complete.
Art is creative.
This is business. Coverage is a tool explicitly designed to save a Development Executive's precious time. That, dear readers, is a subject so tortuously complex that the Oracle at Delphi would shrug in helpless mystification. In other words, a subject for a later column. For the moment, the chief thing you need to know is that the Development Executive is the man or woman who might buy your script.
