I do agree that movies are going by the wayside in terms of being longform storytelling ideas. Building universes in them is tough, unless you have like 30 movies like the MCU.
It's short, compact, discreet story ideas you can hold in the palm of your hands....like Rian Johnson's Knives Out (yes, I used RJ because of how maligned he is by Star Wars fans), which is a murder mystery that takes places over a short amount of time.....that really brings to life the movie genre.
