Extraterrestrial race is stranded on Earth and is forced to live in a slum. The city the aliens hover over is Johannesburg, a point not lost on me.

District 9

The movie starts off in a documentary style, as it moves forward it crosses over to a conventional film. Enjoyed the movie, you never understand the aliens, however you always seem to know what they are saying.  The movie has some flaws, but it worth watching.

7/10 parts of this movie will stick with you for days
