“District 9” does a lot of things right, including giving us aliens to remind us not everyone who comes in a spaceship need be angelic, octopod or stainless steel. They are certainly alien, all right. It is also a seamless merger of the mockumentary and special effects (the aliens are CGI). And there’s a harsh parable here about the alienation and treatment of refugees.Most critics love the movie. As I said in my review, this is a genuinely thoughtful and upsetting film that eventually becomes a shoot-'em-up. That means it's not at the level of 28 Days Later or even (and I know I'm getting myself in trouble here) Cloverfield, which at least stayed tonally consistent throughout.
But the third act is disappointing, involving standard shoot-out action. [...] Despite its creativity, the movie remains space opera and avoids the higher realms of science-fiction.
If you haven't seen the short film that inspired District 9, called Alive in Joburg, you should -- a lot of what makes the feature film great can be found there. And I have to say that the moments that don't work as well in District 9 are nowhere in sight.
