Long time ago, a man called Aristotle noticed that drama has certain rules and he published them in his book called Poetics.
Drama is a story about a hero who goes from point A to point B and on that journey they overcome various obstacles.
That rule is a norm for more than two Millenniums, but the form doesn’t mean anything if the story doesn’t resonate with the audience on an emotional level.
Take a look at Hollywood; they produce hundreds of movies each year and they all follow the rules of drama.
Yet, only few movies are worth of attention and are well received by the audience and the critics.
The form without an emotional story is the same as sex with a prostitute.
