>Computers doesn't understand beauty or emotion, so you need fine grained human control every step of the way.
That's were your wrong. Computers don't understand beauty, but given enough processing power, and sample data they can recreate it.
There's already a program that can listen to Beethoven and reproduce something that even experts can't tell he didn't write.
A movie example: In your movie creator you set up a scene with 2 people talking in a room. The computer has been trained with thousands of such scenes, so it automatically selects the best camera angles and allows the operator some manual control. That will happen at some point.
