I've seen this movie more than once and it was fascinating experience every time. I must admit I haven't read the book so I can't compare them but the film itself is made outstandingly with a style of its own. It creates the whole world that you believe in. The pace of the film, colour and effects, music, great actors, make it an incredible experience even in the 21st century. If you like science-fiction, it's a classic film to watch.
