“.... AI-generated plots are still absurd, from what I’ve seen.....”
Wrap enough special effects, “wokeness” & gratutious nudity around the plot and its a movie market winner !
I suppose you could dose the AI with a database of platitudes catalogued by things like “mood”, “attitude” and “wokeness” and synthesize a dialogue based on what comes out. If the special effects are dazzling enough, no one will notice.
