Too much of anything is not good. Too fast, too slow, too loud, too soft, in this case... too dramatic.
In terms of storytelling, being a bit dramatic is necessary. Have you noticed in many popular movies, the producer would put these words on the poster: Based on true stories? It is NOT the true stories.
Based on true stories means: The story did happen, but there's additional seasoning called.. dramatization to spice up the stories.
Without dramatization, imagine Titanic without Jack and Rose's romance. It will just be... an icy cold movie about a drowned ship.
Here's another example:
Three weeks ago, I was seating in the train, when I suddenly sneezed. The aunty who was seated beside me immediately stood up and walked to the next cabin.
Three weeks ago, when I was commuting to work, it was one of the rare moments I got a seat in a packed train. As usual, everyone was busy looking at their phone. Suddenly, my nose was itchy and I couldn't contain my sneeze. Haatttchewwww!! Right at that moment, everyone looked up from their phones, stared at me for 2 good seconds, and dispersed to all direction. Leaving a 2 meter empty space in front of my seat. Some of the passengers were covering their nose. I was confused. Was my brain defy me from what I thought was an innocent harmless sneeze, turn out is a smelly potent... fart? Moreover, the auntie who was seated beside me was frozen. Her face was as pale as my white shirt. She must be shocked by the loud voice of my sneeze. I was panic. What if she had a heart-attack? What if she fainted? What if her eardrum broken because of me? When I was busy thinking about all the possibilities, she suddenly stood up and dashed to the next cabin. Only few days later I learned about the viral Corona virus and understood what was happening.
