Troubling, but exhilirating More propagandist than its supporters sometimes allow, this is still one of the greatest pleasures in the whole of cinema.If you don't think about the sinister organising force of the film's incessant patterning and connecting, the film is a feast of enjoyment and possibility - a poem of beautiful imagery, gobsmackingly inventive montage, a hymn to artifice and the potentialities of the medium.The film is lighthearted and frequently comic in its depiction of the day in the life of a city.Just don't try to remember that it is also an act of Stalinist centralisation that cares more about machines than people.
