Dances With Wolves has the kind of vision and ambition that is rare in movies today. It is not a formula movie, but a thoughtful, carefully observed story. It is a Western at a time when the Western is said to be dead. It asks for our imagination and sympathy. It takes its time, three hours, to unfold. It is a personal triumph for Kevin Costner, the intelligent young actor of Field of Dreams, who directed the film and shows a command of story and of visual structure that is startling; this movie moves so confidently and looks so good it seems incredible that it's a directorial debut.
