Chances are, by now, you’re wondering what the hell the deal is with District 9. The trailers were cryptic, faux-documentary newsflashes that plunged viewers into the world of the movie without revealing any of the plot. It was a canny move, but a risky one – people were supposed to buy tickets to see a movie they didn’t know anything about, except that it involved aliens and probably symbolized apartheid. You can’t tell from watching the trailer whether District 9 will turn out to be a ham-handed message-fest, a two-hour Halo cutscene, or a thriller as savvy, original and resourceful as the promotion itself. Good news! It’s the third, and in fact, I’d almost recommend watching it with no more information than that.
