at what point does a filmmaker have an obligation to tell the story no matter how ugly it gets?


meaning, a part of me wanted them to shut the cameras off when Q-Tip and Phife got into a physical altercation. But at the same time, if you're making a documentary, does that part of the story *need* to be told? Are there rules that go into it, and a director can decide that there are things the audience doesn't need to see?
