District 9 is very blunt, on-the-nose socio-political commentary. It is, again, everything people seem to be worried about -- a blatantly political message underlying entertaining genre fare.
Movies have always been used to express social and political views, and it's been a staple of science fiction since its inception. The entire genre is regularly used, and really best used, to recontextualise contemporary problems in a palatable way that gets people to think. Metropolis isn't just a movie about a lady robot.
If District 9 is somehow the bar for subtlety, what are people honestly expecting in this TV series? How much more overt can you get?
