Ford v Ferrari opens with Ken Miles saying the engine sound at 7000 rpm is the sound of God. Mangold uses that line three times across the film, each one further from triumph. The script makes a religion and then dismantles it.
If a location could be swapped with any other and the scene still works, the script is leaving tension on the table. Space should create leverage, not just atmosphere.
Killers of the Flower Moon spends three hours building Ernest as a man who almost knows what he is doing. The courtroom scene is the moment the screenplay stops protecting him. The audience has to keep watching him after.
Children of Men does not explain collapse first. It lets routine rot in public until one violent moment confirms what the audience has already felt in the air.
Banshees of Inisherin is structured as a breakup screenplay where one party is a man, the other a man, and neither is romantic. McDonagh asks the audience to take male friendship as serious dramatic stakes. The whole script earns it.
A good midpoint does not only reveal information. It changes what the protagonist can responsibly do with that information. Knowledge without new pressure is just plot storage.
