It is in the belief of this film maker that they are doing something good, making art, by reaching into the chasm of artlessness and apathy for inspiration.
How do you convey that without showing them pouring hours of time into prompting though? One can write a book chapter about prompting AI that is engaging to read because we can use 1st person perspective or 3rd person omniscience to hear the thoughts and feelings of the character. A movie forces us to look at the room, and rely on either narration or exposition to convey feelings.
Not saying it's impossible to write a good story about it. But I think film would be a particularly challenging medium.
