And second, tension is needed to compel a reader’s interest. With the introduction of tension, the story really starts. Up until then, we just had a collection of facts. There was no compelling narrative. Note that I could have arranged those facts in any order, without making a significant difference to your interest.
I agree that tension was the missing element. I believe that if stories did not have tension and contained a mere collection of facts, the audience would be bored. This aligns with my understanding of the traditional story-telling structure, also known as freytag's pyramid. I think most stories follow this structure, as they have exposition, an incident, rising action, climax, falling action, and then finally a resolution. If a story did not have any bumps, or problems or tension on the way, the flow of the story would be somewhat linear and uninteresting.
