The more people you have working on anything artistic, the more average the result is going to be. The possibility to crowdsource books has existed for thousands of years - all you'd need to do is make a group of people sit together in a room and try to collaboratively write such a book. But it has never worked with that. And it will never work, because when too many people collaborate, they tend to stay safe. They don't do new things. The only way to crowdsource is if you make several people work parallel on independent parts of the project, and then mix them together at the end. For example, you have 15 people who are working independently on the soundtrack for the movie, and then a panel of judges picks the best soundtrack. If you let people vote on the result, they won't choose the best, they will choose the most familiar. Crowdsourcing can work, but you still need to specialize people within it, and then give them creative freedom free of criticism from others.
