Not trying to convince you otherwise. But movies are audiovisual media. It’s right there in the name. So they visuals and the audio are a big thing for that medium. Radio theater had no visuals, but they used sound desing to elevate the medium. Books have no audio nor visuals, so they focus on delivering a great story with great dialogue.
Every medium has its strengths and weaknesses and every work within those mediums should focus on them. If there’s ever a movie that is 5hs long with an amazing story and superb dialogue… then it should’ve been a book.
My point is that it’s ok not to like it. But the idea that a movie should have “good dialogue” is a bit misunderstanding what movies are and what the medium is. You can have a good movie with little to no dialogue or a very very basic story.
