To begin with, District 9 is an amazing film. It is a refreshingly new idea. Before i go any further, i must warn that this review contains (vague) SPOILERS.
Unfortunately, such narrative brilliance is over-shadowed by extreme acts of violence and excessive swearing. Sex is not a major issue, there are a few references to "interspecies prostitution" and one, rather cheesy (it was more comical if serious) image of a fully clothed man behind an alien in the process of thrusting. Beyond that, there is nothing graphic in regards to sex and nudity.
In the case of cursing, there are approximately 100 uses of the F-word as well as infrequent use of the s*it and other curse words. The F-word is the dominant curse word (and adjective!) in District 9.
Now, the biggest issue of the film: violence. The violence is plentiful and gory, with humans and aliens alike exploding before your eyes. There is also one instance where a man gets his arm shot off and then crushed and another where you see a man's head explode and the blood splatter around his feet. The two executions of aliens in the film are probably the most distressing acts of violence being that they are killed without reason. Some of the gang members are also shown to be eating the raw, severed limbs of an alien (albeit very briefly). The viewer is also taken to an experimentation laboratory where aliens have been hung upside down, cut into pieces and a multitude of other grievous acts. The last 15 minutes of the movie is very action heavy with lots of shooting and one character having a large spike shot into their head before it detonates and their head explodes. Other disturbing, but not violent per se, scenes involve the ongoing transformation of a man into an alien and we see the exoskeleton slowly growing from beneath his skin, causing abnormal wounds to appear on his flesh. Two of his finger nails come off as well as a few teeth fall out.
The verdict? District 9 is quite an amazing film that is original and keeps you entertained throughout the entire journey. That being said it is extremely violent and includes a lot of swearing. I can't actually say I recommend the movie because, due to the content, I don't recommend it to anyone. View at your discretion.
