You might find it fun if you deliberately see how he uses frames and juxtapose them to illicit a meaning. He was not instinctively doing it, all of it is mathematical.
you know my just a regular old movie lover so I might even have realized about the frames... perhaps the beauty of the movie lies in there... what moved me is the story and certain points such as the scene where the mother was climbing the stairs with her son brutally injured (or dead) and the moments before the mutiny on deck... the film is extraordinary but these few moments stood out
That scene is iconic! As it incorporates and contains the feelings and desperation of the mass.
