At one point, Bird talks about how some makers of animated movies create scenarios that are too fantastic and then are, later on in their films, unable to interject a true sense of danger into the plot.
The mistake that people often make with animated films is that they love the gravity-defying aspect of it. But, if you defy gravity and then later on need to feel danger, you have a really hard time convincing the audience.
Contemporary superhero movies, even the good ones, often have this problem, and I wonder if it’s because they are essentially made like animated films with too much of the gravity-defying aspect. With CG and flawless green screens, you can essentially make anything happen on the screen, which somewhat counterintuitively lowers the stakes of what you’re watching.
