You have to not be arrogant and say you know better, and you have to not thwart their creativity because they are creative people and they have a very different point-of-view than a filmmaker on how to get people in the seats. So, it's a balance, like everything in life, between keeping your focus and being overly constricting. So, if you want to be a filmmaker, you have to realize what a long arbiter a movie is cut of and shaped on, how many phases there are to it, and how long you have to be totally focused on your story and the movie itself, and how it seemed one way but making a film is really trench warfare.
