Every now and then, a film comes along that both defies and compels description. "District 9" is one such movie: a science-fiction action vehicle so brilliantly and fully imagined that real life, when it resumes after the credits, arrives with a new sense of dread.
You may well believe that a huge alien mother ship has been hovering over Johannesburg for the past 20 years. You'll feel sick in your gut at the events that occurred there. Revealing much more of the plot, at this point, would ruin the sucker-punch force of its storytelling, but people who can't stomach violence should keep their distance; be advised that heads explode, limbs detach and bodies go sploosh in an instant.
