“The single-most important thing was the art of working in the studio system,” Nolan told me of his experience with “Insomnia.” “It takes time to learn how to take notes. In the corporate structure, the people giving you the notes are not responsible for the final product. You are. It’s not their job, it’s yours. When you’re taking notes, it’s possible that you’re having an interesting conversation with a very smart individual and everything they’re saying is correct. But they’re wrong. So you have to go back and approach it from a different angle.” He continues to treat executives as, essentially, representative filmgoers. At a development meeting — at, in other words, a conference-room table — before “The Dark Knight,” he had to explain the Joker’s motivations. “Execs are very good at saying things like, ‘What’s the bad guy’s plan?’ They know those engines have to be very powerful. I had to say: ‘The Joker represents chaos, anarchy. He has no logical objective in mind.’ I had to explain it to them, and that’s when I realized I had to explain it to the audience.”

And so occurred the fabulous "some men just want to watch the world burn" speech.
Notes can be excellent. There are two kinds of notes: notes from people who understand story, and notes from everyone else. Everyone else can often include people with power over you and the money to fund your thing.
If someone who understands story gives you notes, then you might benefit from executing them.
If your note-giver is not someone who understands story, then executing the notes might make your script worse. The solution is not "doing" the notes but "addressing" the notes. . "Addressing" the notes is harder. It means finding out where the gap occurs between your vision and the reader or viewer's experience. Note-givers usually focus on where their experience is bad. "This scene is too slow; trim it down." The scene may be too slow, but maybe it's because we don't care enough about the main character; making him more compelling 20 scenes earlier fixes the scene. Or maybe it's because the scene never really gets to the meat of the drama. Sometimes it needs to be longer, not shorter, to build up steam.
Unless you are independently wealthy, your creative career will always depend on your ability to address notes successfully, without always executing them as is.
