I do need to put a disclaimer here though. These guys that made the video were able to get some amazing footage, but I have to say that they did it without any cultural awareness of North Korea, and Korea in general. It seems as if they made the documentary just to prove that they could do it, and not for any actual interest in North Korea and the North Korean people. How difficult is it to learn how to say hello and thank you? They sort of make a mockery of the people that they meet, and if the North Korean government ever sees this video (which they probably will) it's quite possible their guides and their guide's families could be sent to prison, if not killed. That is the reality of North Korea, and they did not take this fact into consideration when filming.
That being said, it is still an amazing video to watch, and it gives you an amazing perspective into the country.
