I loved 99% of that movie. Except the bad guy. I try not to focus too much on bad dialogue but some of the lines he has on the final phone talk is so bad it really damages the movie. But it also has one of my favourite lines of the last 5 years.
“What’s happened happened, which is an expression of faith in the mechanics of the word. It’s not an excuse to do nothing.”
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.
