Because liking the person we go on a journey with is the single most important element in drawing us into the story.
“What is it?” is the name of the game. “What is it?” is the movie.
And concentrate on writing one sentence. One line. Because if you can learn how to tell me “What is it?” better, faster, and with more creativity, you’ll keep me interested. And incidentally, by doing so before you start writing your script, you’ll make the story better, too.
The number one thing a good logline must have, the single most important element, is: irony.
