I've yet to see continuity working. Small clips is one thing. To have the same character, wearing the same clothes, revisit environments, with the same lighting and post processing is very different.
That and control, there's an enormous difference between letting a model just YOLO a prompt, filling in 95% of the details with vaguely plausible whatever, and getting a model to execute on a meticulously planned out shot with every last detail in order.
