an alien movie

I watched a movie called 'District 9'. A space ship of the aliens called the 'Mothership' docks over an area of Johannesburg (It isn't on land , it looks like it's suspended from somewhere). And the aliens take refuge in a block called district 9, which looks similar to the slums in India.And inside this slum, some of the Nigerians take shelter too and carry out some business in with the aliens. They supply food ( meat of the animals) to the aliens in return to the weaponry that the aliens give them.

A reporter from an orgranization called "MNU" is chosen to initiate the eviction of the aliens to an area far away from the city. As he goes there with his team and starts his attempts to initiate the eviction plan by first notifying the aliens about this and getting a sign on a form!, he gets in contact with a canister filled with black fluid. This canister is supposed to be the fuel for the smaller space ship which is used to fly the aliens to the mothership so that they can go back to their planet. The ever alert reporter quarantines the canister ( This fuel is now in the hands of the "MNU"). The reporter goes back to work and starts feeling sick. And eventually, his hand mutates to an alien hand. And he becomes the object of many tests. When he is about to be killed , he fends the doctors, kicks them all around and then escapes from the lab. He then hides in only place possible, in district 9. He again meets the aliens from whom he stole the canister and comes to know that his hand could be fixed if the aliens could take him to the medical facility in the mother ship. But unfortuatlely, the fuel which took 20 years to make is in the hands of the "MNU".

The reporter now wants to get the fuel back. He along with the alien friend take the weaponry and go to the "MNU" to get the canister. As they enter the building, the reporter fires the weapon, (alien weapons are very cool) and a security person is shredded into pieces. Then the alien who also wields a weapon says "I thought ,you said we aren't going to kill anybody". This got me thinking.... Now I am bit tired to write about why it got me thinking. So i ll try to write it some other time.
