Because when people praise movies and its directors, the impression I get is that the directors are the main reasons why a movie is as good (or as bad) as it is, like they're more responsible for the story you're going to watch than the writers, the storyboard artists, and the post prod team.

Obviously, I'm not the mxycan with a film-school background, but the way I understand it is that the director's job is to tell what an actor does in a scene, and if needed, give him the proper motivation. I don't know what else, does a director also shoulder the responsibility of lighting modifications, set design, script revisions? Inquiring minds need to know.

I'm just wondering why directors - who I think are partly responsible for the interpretation of the story - get more rockstar cred than the people responsible for the story in a movie. When movies are pimped, "directed by" seems to have more weight than "written by"
