FUTURE IN DOCUMENTARIES?

One dream that I have is to make a documentary. One stringent requirement I would have is that the piece will be as accurate as can be. I have watched some documentaries that do not delve deeply enough in their subject. Some take liberties to add things that are hearsay or are downright false. Documentaries should be informative and creative, They should also inspire those who watch to act on resolving a particular issue.
