We got sucked in and watched the movie to see what all the controversy was about. The movie is pretty disgusting. It was designed to be highly offensive. There was no need to portray Kim Jong Un in this movie.
Our opinion was that North Korea had nothing to do with the hacking of Sony's computers. The attack and resulting publicity has the result of attracting more viewers to the movie, all intentional.
It defies belief that any Country has the ability to hack into any large corporation's computer system. If this is the case then we have a serious problem on our hands.
Obama expressed his concern about freedom of speech. If it was himself that was portrayed in a movie like this instead of Kim Jong Un I don't doubt that there would be many people in the USA expressing how sickening this movie was.
North Korea has a relatively small population and a limited amount of funds, providing a good opportunity to experiment with this type of propaganda.
