This movie fallows Kobus a young man who lives in Johannesburg but a alien ship arrives over Johannesburg. Now the humans make them live in a ugly poor neighborhood called District 9, but the aliens start fighting the humans because their treating them meanly, differently, and poorly. In the mean time Kobus gets sprayed but alien goo and then realizes that the goo makes him turn into a alien. The violence is this movie is extremely graphic and very gory, aliens kill humans in many different ways humans die by getting stabbed, shot, blasted to bits, and murdered by axes, Kobus also cuts his fingers, and arms to so he can get is alien body parts off. There is constant swearing. Otherwise this movie is fun, entertaining, awesome, fantastic, and enjoyable. Heres my age rating, off 2-14, iffy 14-16 on 18+. My rating:R for sequences of strong gory/graphic/disturbing sci-fi violence, sequences of disturbing action, bloody images, pervasive language, and thematic material.
