This documentary is very important. It helps to show the manipulation that must go on daily in North Korea. The constant reminders to "be more joyful" or to act "with patriotism" demonstrate this. It is well worth watching, if for no other reason that to see how Orwellian the world can become if allowed.
But by the end of the film, I felt sympathy for everyone involved. The children, the parents, and even the handlers.
While the children and parents are being directed by the handlers, the handlers are following the directions of those above them, and so on. These handlers are simply people who want to do their jobs and avoid punishment, the same as everyone else. You can see it, especially in one scene towards the end, when they are tucking Zin-mi into bed. The North Korean director looks as tired as anyone else, and as downtrodden. Everyone has a role to play, it seems.
The film is conflicting because you have to wonder what could happen to these people for their failure to censor this film adequately. Or for their failure to act appropriately patriotic in some of the takes that the censors didn't want us to see. We have to hope that the honesty of this film didn't lead to anyone coming to harm.
