Oh, FFS...this is just crazy. Just because a movie takes place in, say, South Africa, doesn't mean South Africa should be allowed to sue the movie's developers just because the developers don't paint South Africa as a Happy-Happy-Fun-Time sunshine land full of rainbows and flowers. That is to say, when depicting South Africa, the District 9 developers weren't going out of their way to portray the whole place as horrible, but if they had, don't you think any of the dozens of critic reviews out there would have mentioned it?
