Staging in Doc?

Of course we all agree that staging is wrong, it's lying. It's deceiving your audience that what they're seeing is the truth, when it's not. Last night I saw a documentary and it obviously staged some events but at the same time still was able to tell a great story. I understand that documentary film is a little different but coming from straight news, I was still left with a little squimish feeling in my stomach. I couldn't decide if what I was watching was completely acceptable. Of course the story told an incredible story and like I said, it was obvious that some of the scenes had be recreated. Do we measure our standards for journalistic integrity differently in comparison to different media?
