Anyone seen this yet? I saw it last night and was completely blown-away. Like "V" was a commentary on the Nazi invasion (albeit a cheesey one), D9 addresses apartheid, the Johannesburg backdrop being perfect for the plot. This film is genuinely heartbreaking in sections...you won't believe how sympathetic you'll feel towards 7 foot insect aliens. A lot of it's shot in a sort of documentary style too and it really works, lending an air of gritty disturbing realism. One of the finest sci-fi flicks I've ever seen, and I've seen 'em all.
Plus it's got cool alien guns and explosions in it. Hooray!
