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...
North Koreans are people too, and even if the tour is scripted and carefully controlled, the people he met were still real.
Edit - this is a fascinating documentary by another tourist who went to the DPRK: http://documentary.net/dprk-the-land-of-whispers-north-korea...
Again, lots of curated 'positive' images for the regime, a few hidden camera moments, and some fairly real commentary from the guy who filmed it.
