The Heart of every documentary: always start with the why

There is a mistake that many filmmakers-even experienced ones-make before they even turn on the camera: forgetting to ask themselves why they are making that documentary. Not “what we want to show,” but why this story needs to be told. The difference seems subtle, but it changes everything.

This article stems from exactly that: from the belief that a documentary without a solid why is like an aimless journey. Maybe the scenery is beautiful, but you don't know where you're going and, in the end, you don't remember anything.

One question. One answer. everything else is noise.

Every documentary worthy of the name starts with a question. Not an academic question, but one that burns - something the viewer feels is his or her own from the very first minute. And throughout the film, an answer is sought.

This is the narrative contract with the viewer: follow me, I'll take you somewhere.

Take a topic like the cost of health insurance in Switzerland. You could make a documentary that explains the national health care system, the laws, the rates, the average premiums. Useful, sure. But also terribly cold. Chat GTP does it better and in less time.

Or you can pick one person-Mark, 37, self-employed, who every month has to choose between paying his health insurance premium or going grocery shopping-and tell how that amount of money is changing his life. That is a real question: what happens to a person when the health care system becomes a luxury? And that question has the power to keep the viewer glued until the credits roll.

The Why is the engine, not the decoration

The protagonist's “why” is not a narrative detail: he is the engine that moves the whole story. It is he who creates tension in the highs, who makes the lows bearable, who makes the audience really care about what happens.

Always ask yourself: what does the protagonist want? Not in the abstract-he wants “justice,” “happiness”-but in the concrete. Does he want to pay less? Does he want someone to listen to him? Does he want to show that the system is broken? This specific desire is the compass of the story.

What if your documentary is about a product or service? Same principle. The why becomes: how does this solve a real problem? If you can show that the viewer-or someone they know-has that problem, too, you've already won. You're not selling, you're offering an answer to something that already hurts.

Know the destination before describing the trip

There is a phrase we often use here at StoryLab: you have to know where you are going in order to describe the road well. If you are not clear about where your documentary is going, you will struggle to build a coherent narrative. Scenes pile up, but they don't connect. Interviews multiply, but they don't build anything.

Knowing the destination does not mean revealing the answer right away - in fact, it is quite the opposite. It means revealing the answer slowly, in pieces, letting the viewer build it with you. Each scene should add a piece. Each testimony should open a new question or partially close the previous one. It is this progression that keeps the tension high and creates growing empathy with the protagonist.

If the answer comes too soon, the journey loses meaning. If it never comes, the viewer feels betrayed.

Honesty first: the price of trust

There is one last element that makes the difference between a good documentary and a really powerful one: genuineness. And genuineness means having the courage to leave out one's own assumptions.

Do you have a thesis? Fine, keep it as an internal guide - but don't impose it. Let the story unfold, even if it surprises you. Include different voices, opinions that perhaps contradict the direction you thought you were taking. That balance doesn't weaken the documentary: it makes it credible.

The public feels it when someone is honest. And when it hears it, it lowers its defenses. It trusts. It connects with the story and the person who told it. That is the most valuable result a documentary can achieve -- not the likes, not the awards -- but the feeling of the viewer who, in the end, thinks: This story has changed something for me.

And it all starts with one word: why.
