Okay, I agree that a foreign government shouldn't be hacking corporations, which as the Supreme Court tells us, are people too.
But it strikes me that a movie whose plot revolves around a plan to kill an actual, non-fictional human being, is, to say the least, somewhat tacky. Imagine the response by this country's right wing (the sector most exorcised about free speech rights in this case) had North Korea, for example, put out a movie about killing W while the boy-king was still in office. It would have been a strange situation, because for once the right would have been right.
So, North Korea bad, but the movie bad too. Kim Jong- Il is a miserable excuse for a human being, but he is still a human being. Mock him by all means, but don't make a movie about killing him.
