Peter “Lord of the Rings” Jackson gurus a sci-fi project written and directed by Neil Blomkamp about the landing of Aliens in Johannesburg, Africa. Part documentary, part movie, this shaky-camera-all-over-the-place feels a bit like “Cloverfield” but far more intelligent.  The aliens can’t go back – they’re here to stay – and their ship is inoperable. They’re skinny, they’re hungry, they look like giant pieces of steel shrimp cocktail, and they come equipped with weapons that would thrill any terrorist. Always creative in story, and very political, at times the movie isn’t as exciting as it could be.  That said, it’s smart and it’s different, and while there aren’t any recognizable stars – Sharlto Copley plays Wikus (sort of a character out of television’s “The Office” he can’t think beyond his corporate rules.)  That said, this is certainly a thinking man’s solid science fiction film.
