I think Neil Blomkamp might be a wizard. His expertise has always been in cinematography and SFX, and it shows in District 9. His alien future is a dump, but it's a supremely believable one. From the media circus surrounding the aliens to their treatment by humans and the mechanisms of military technology, District 9 feels real even if it's stretching the limits of what's possible to put on screen. Also, Sharlto Copley is a treasure.
