Sharknado is the same movie as Titanic, only with more sharks
by Pierre Morsa —
Believe it or not, all American movies rely on the same formula; that formula is so sacred that scripts will get rejected if they stray from it. Whether it’s a psychological drama like American Beauty, a sci-fi movie like Star Wars or an action movie like Mission: Impossible, the same structure, plot points and character development techniques are used. I’ll just take one as an example: the hero, the main protagonist, is always an orphan, literally or figuratively, or experienced a personal drama; it is supposed to give the character more likeness.
