Kin-dza-dza! - Georgiy Daneliya
Even it’s the one of the most underrated movies in the world and probably never screened in Europe, it’s a cult movie in the ex-Soviet Union.
Even it’s quite far from a “Blade Runner” approach and doesn't look like a “Mad Max” even remotely, this is the best sample of comedy and absurdity in sci-fi narration with a pinch of melancholy and political-social criticism.
Don’t expect any special effects and any particular dialogue, expect something of bizarre, imaginative, awkward, weird, cyberpunk… something like a melting pot of strange tastes.
