I think the author has a bias to show North Korea in a positive light (the pristine pictures, jabs at commercialism, readiness to accept a tour as fact), or, at least, tries to show a generous understanding of such a country and its culture. Personally, I think this does a disservice to actual testimony from former citizens [1][2].
It's giving out a good light on North Korea saying overall it's different from our systems but not in bad way just different. Like the metro, where he is saying there is 16 stations and 3 lines and regular koreans are using it while we tend to think otherwise. Or, the final show that's one of the best he has ever seen. Like forgetting the slave labor behind it. Oh, no yeah, only one photo describing slave labor when he is talking about the south korea sending work to the north. Like if the south korea is responsible of the slavery of the north...
