This is the best answer I've seen, but I think what was demonstrated is miles away from this. A lot would need to be able to be specified (and honored) from the prompts, far more than any examples have demonstrated.

I'm not against tools for directors, but the thing is, directors tell actors things and get results. Directors hire cinematographers and work with them to get the shots they want. Etc. How does that happen here?

Also, as someone else mentioned, there is the general problem that heavily CG movies tend to look... fake and uncompelling. The real world is somehow just realer than CG. So that also has to be factored into this.
