Cualquier teoría sobre los paradigmas y los modelos infalibles de redacción que sirven para alcanzar el éxito comercial es un disparate. - Robert McKee

Day after day we seek an answer to the ageless question Aristotle posed in Ethics: How should a human being lead his life? But the answer eludes us, hiding behind a blur of racing hours as we struggle to fit our means to our dreams, fuse idea with passion, turn desire into reality. (...)
Traditionally humankind has sought the answer to Aristotle's question from the four wisdoms - philosophy, science, religion, art - taking insight from each to bolt together a livable meaning. But today who reads Hegel or Kant without an exam to pass? Science, once the great explicator, garbles life with complexity and perplexity. Who can listen without cynicism to economists, sociologists, politicians? Religion, for many, has become an empty ritual that masks hypocrisy. As our faith in traditional ideologies diminishes, we turn to the source we still believe in: the art of story.

Many producers state without blinking that the audience wants a happy ending. They say this because up-ending films tend to make more money than down-ending films. The reason for this is that a small percentage of the audience won't go to any film that might give it an unpleasant experience. Generally their excuse is that they have enough tragedy in their lives. But if we were to look closely, we'd discover that they not only avoid negative emotions in movies, they avoid them in life. Such people think that happiness means never suffering, so they never feel anything deeply. The depth of our joy is in direct proportion to what we've suffered. Holocaust survivors, for example, don't avoid dark films. They go because such stories resonate with their past and are deeply cathartic.

Generally, great writers are not eclectic. Each tightly focuses his oeuvre on one idea, a single subject that ignites his passion, a subject he pursues with beautiful variation through a lifetime of work.
