Dialect can be a powerful tool to help writers bring the characters they have created to life. A writer might use dialect, along with accent, to distinguish a character's unique way of speaking and in doing so, illustrate their place of origin, cultural background, or social class.
Some people define "fake news" as news that is created to make money. Other people broaden the definition to include deliberate spread of misinformation to persuade someone. "Language, statistical figures, graphics, and other forms of presentation intended to persuade by impressing and overwhelming a reader or listener with a blatant disregard for truth and logical coherence." (Carl Bergstrom)
So when people make tragic movies there is always a theme to them or a goal the author is trying to get out. It might be a sad movie that a lot of bad things happen but in the end usually something good comes out of it and that can help people, or can even be more interesting, to be a successful story.
