I watched that shit yesterday with the girl's family. First impressions are that it was definitely funny. I laughed a lot. But I don't know that I would laugh as much a second time, and maybe not at all a third time.
Overall, it's worth checking out. But I'm not sure the replay value is there.
And honestly, I'm not sure I get why North Korea got so butthurt. They really didn't make Kim Jung Un look THAT bad in my opinion. Obviously, any negative connotation towards him would be seen as bad but they just have their pussies in a bunch.
