There is a reasonable expectation that documentaries should be unbiased depictions of whatever they happen to be about. When you set out to make a documentary it's expected from you not to misrepresent what you know about the subject matter.<p>I don't expect it to happen 100% of the time, but that's what separates good journalism from Fox News (or NBC, according to you). I take all journalism with a grain of salt, but I also expect journalists to at least try to properly inform their audience. You know the saying: with great power comes great responsibility.
