I wouldn’t say a strong storyline is essential for every movie. There are genres, like slapstick comedy or experimental films, where the plot takes a back seat to visuals, humor, or atmosphere. Many viewers are drawn to movies for their special effects, music, or overall style rather than the narrative itself. In fact, some blockbuster films achieve huge commercial success despite having basic or predictable storylines, simply because they offer an entertaining experience through action or spectacle.
