Michael Palin did a great documentary on North Korea that I watched some years ago. It wasn't completely without bias but I thought he did a pretty good job. He allowed the people to speak and give their own first hand opinions as actual residents of NK.
Something that stuck with me was one of his guides, a young woman, talking about how people in NK don't necessarily have the same values as people in the west. We think they're oppressed, that they want the same western style liberal democracy as us, and that they are all brainwashed so they couldn't possibly be giving their own opinions. We like to think they're wrong about everything and that we're right.
NK isn't a utopia. Nowhere is. But it's not for us to tell them what way they should live.
