A perfectly fascinating piece of science fiction fantasy, it is visually impressive, well written and well directed. The film has certain moments that can be described only as classic, however the overall film is quite imperfect. There are some really striking flaws such as poor dialogue recording, an ending that is by far too roundabout, and in fact a whole end section that is not nearly as interesting as the beginning of the film. Either way, there is still however a lot to appreciate in the experience, including the spectacular sound effects, which won the film a special achievement Oscar.
