This is a question of creativity.
A lot of books and even movies remix what has been done in the past. They take what has worked and make their own.
For example a lot of Starwars fans thought A New Hope was very similar to the story plot of The Force Awakens.
My advice for you would be write down your favorite scenes in books you read, shows you watched or movies you saw. Then from their take the elements that you loved and make it your own.
Another suggested that helps is to follow the basic frame work of a story. There is a beginning where you introduce the setting, main characters world. Then there is rising action, building up to the "climax." The climax changes everything. From there you have falling action where your story starts to come together. Finally the ending. People love to feel satisfied like their is a happy ending, but if you leave a cliff hanger you will have your readers wanting more.
