Why do American movies always have to have a love story?

One of the reasons American movies always have a love story is because it is a universal theme that most people can relate to. A love story can add depth to the plot and create an emotional connection between the characters and the audience. It can also attract a wider audience, including those who may not be interested in other aspects of the film.

Another reason is that love stories have been a part of the film industry since its inception. Hollywood has long been known for its romantic movies, and many of the most successful films of all time are love stories.

Finally, it's important to note that not all American movies have a love story. There are many different genres of film, and some focus on other themes, such as action, adventure, or comedy.
