They are all using the same system of production and that is a cookie cutter/cut & paste system. It has to be, because these productions are huge. The way that movies are shot requires trades people each in their own unions or guilds who work according to formulas and regulations. How the lights, camera, sound are set up is according to the system established by technicians. Line producers dictate shooting schedules and locations. Because so much money is on the table--even for a $10 million movie, it's a huge investment--they operate according to rules that no auteur has any control over. If a director has an idea for how he wants to create a certain look, it's the crafts people who used their training to figure that out, according to what's been established for film production. But it's all an assembly line industrial product.
Compare that with comic books. One individual can create and publish a comic book from start to finish. Even for big publishers, most of the work on a comic book is done by less than ten people. So if someone has a creative idea that breaks all the rules--there's little to stop them. It's not going to cost a fortune and that one person can do it all on their lonesome. Even a small budget movie requires the input of many people. The more labour-intensive a movie becomes, the bigger the budget--and the more money spent on the movie, the safer it has to be. Investors aren't going to throw their money away on an experiment that has no hope of being popular. Mainstream movies all have to be within a narrow scope of entertainment and not take chances.
There have been filmmakers like Norman McLaren, who could make a movie all on his own except for the small cast he used--NEIGHBOURS (1952) had two actors, Jean-Paul Ladouceur and Grant Munro. With today's technology, there are people who can make movies at home, with their computers, without needing a cast or crew and for very little money. That's the future. I think eventually we will all be making our own movies at home, without any directors, actors or crew getting in the way.
