From NetFlix:
When aliens land on Earth, global business conglomerate Multi-National United forces them into rigid containment zones where they are compelled to labor, even as MNU commandeers their otherworldly technology for profit. As tensions build between human and non-human races, a rogue agent leads a resistance movement against MNU’s ruthless consolidation of power. Neill Blomkamp directs this cinema verité-style sci-fi thriller.
As one of the more original sci-fi films I have ever seen, the best adjective for this film is FRANTIC. By using hand-held cameras the constant tension never lets up. Sharlto Copley (who is really from Johannesburg, South Africa) is the perfect choice for the honest, well-meaning pawn of the weapons manufacturers. He is jittery and always a giant bundle of nerves. At first I groaned because the “prawns” (aliens) just looked so stupid. But soon even they fit perfectly into this tale of military-industrial suppression.
Subtle this movie is NOT. In a way the film is one big action scene from beginning to end. In this respect it might remind you of a car chase B film. Therefore, to enjoy this adventure you must like science fiction, action films, bloodshed, violence, and noise. What more could you ask for ?
And tell me, what is going on in the last scene ? What exactly did happen ? In fact, if you want to read a detailed spoiler see wikipedia.
