I want help to answer the problems below:

Recently, with the introduction of directors like Michael Moore and Morgan Spurlock, the common purpose of documentaries has seemed to change. Is it immoral to encompass an agenda when filming a documentary? Should the agenda of the filmmaker be obvious whenever viewing a documentary, obscured, or nonexistent? describe why? Historically, documentaries are seen as factual representations of life. Do you feel this is still the case? Is a documentary still a documentary if any features are staged? Do you think the presence of filmmakers have raised or reduced the popularity of documentaries? describe why?
