Aka, the model of the director or even the show runners in this case having an "artistic vision" and forcing everyone to that vision's will, by being a bit of a dictator is inherent in the design.
But lately I've been noticing this model has become more and more prominent lately, while in earlier times I believe there was more collaborative effort.
i think this was a highly astute, and very important point.
Think how good "The Empire Strikes Back" would have been if Ford doesn't tell Lucas to shove his hokey dialog where the sun don't shine, and give the patented, "I know" response to Leia in Bespin. That was a case of people coming together to make something great that would become timeless. What you see so much now is less focus on the collaborative effort and more importance given to the opinion of one person behind a camera/computer and the actors forced to match their vision instead of building something together (i think the Hobbit trilogy is another example of this, where because the original trilogy was so good the cast of the sequel just followed the dictator, err, i mean director, instead of creating magic on screen with the ensemble).
It's a model that became more of an issue when Baby Boomer directors grew older. They had a taste of the collaborative system when younger & decided to shape their vision more "purely" after they got more clout to "throw their weight around", so to speak. The trend has only gotten worse with Gen X directors behind the camera, as they take the Boomer model and make it more... Draconian. :/
