Good history with a mind blowing plot... sometimes a hard to believe it's all true, and that facts really happened as they are being told. But it's worth watching even without having that much clarity, for the boldness of the movie makers and the footage recorded. As everything else regarding North Korea, it's hard to fact check. So basically you have to put some faith on the storytellers and believe that what they're saying it's true and unfolded the way they show.
