Films are art. You have to let the artists decide what the work they are making will be.
When you watch a movie, you are engaging with something specific someone made. You aren't watching a genre. You're watching a film: an individual, singular film, made by specific people at a specific time in a specific style for specific reasons.
I think the MCU-ifacation of movies is affecting how people receive & interact with movies in a way I very much dislike.
