Flash forwards are often employed in television shows and movies to break up the monotony of a linear narrative, add an element of surprise, or to provide viewers with a preview of what's to come. For example, a flash forward might be used to show a character in a dangerous situation, hinting at future events, or it could be used to show a happy ending, giving viewers hope for the future.
It's important to note that flash forwards should be used sparingly and judiciously to maintain the overall coherence and structure of the story. Overusing flash forwards can confuse viewers and make it difficult to follow the main plotline. As with any storytelling technique, flash forwards should be used when they serve a specific purpose and contribute to the overall narrative.
