One movie could be set in a post - apocalyptic world and the other in a bustling metropolis. The settings, characters, and storylines are all different. You can pick up on different writing styles, directorial choices, and acting performances. This broadens your cinematic knowledge and makes you more well - rounded in your understanding of movies.
