If 'Monster' is a book or a movie, the true story could be about a person's struggle against some kind of inner 'monster' like addiction, mental illness, or a difficult family situation. It could also be about a real - life encounter with a dangerous or disturbing individual. For example, it might be inspired by a serial killer's story, with the author or filmmaker adding fictional elements to create a more engaging and thought - provoking narrative.
Well, one of the key elements could be the setting. If it's a dark tale, the place where the story unfolds might be gloomy, desolate or full of an air of mystery. Also, the characters in the story apart from the 'monster' are important. Their reactions to the 'monster' and how they try to deal with it would be a crucial part of the story. And of course, the true story it's based on would have provided some sort of framework, like a real - life crime or a strange occurrence that inspired the whole concept of the'monster' in the tale.
The true story can bring a sense of authenticity and gravity to the overall atmosphere. Since it really happened, it makes the dark elements seem more real and palpable, enhancing the feeling of dread and unease.
One way the fictional adaptation enhances the true story is by adding dramatic elements. For instance, it can create more intense characters. In a true story, people might be more ordinary, but in the fictional 'Monster', they could be made larger - than - life, with more extreme personalities. This makes the story more engaging.
