Let’s say your child wants to be an actor. One way to make this happen is to be a successful actor yourself - require your children to be cast in the film in return for you starring. This is how famous acting families pushed their kids forwards, including Nicholas Cage (Coppola) and Jeff Bridges.
More relevant for HN is rich people. So you are tech rich and your kid wants to act. Fund the movie on the condition your child acts in it. That is the way since movies began.
The customer of such a movie isn’t the audience but the wealthy patron sponsoring the movie. I suspect this self-promotion motivation is a large reason why so many movies are so bad.
- making movies is hard. A lot of things that require years to master need to go right. A *ton* of tech is involved.
- making movies is expensive. Money alone won't make you a good movie, but many productions are so on the edge that some choice they had to make for monetary reason will cause the bad.
- making movies is complex, that means making a masterful one requires multiple botched attempts and experiences by all people involved. These botched attempts are also what you see.
