You are comparing apples and oranges. Brando was an actor and a very talented one who did mostly dramatic parts. Woody Allen is an Actor, Director who does mostly comedy but also good drama. He is one of the real geniuses of American cinema arts and you cannot even scratch the surface of what he has done by watching one movie that he has directed. I will give you a list of movies to watch which show his scope and talent and then after watching them you come back and see what you have to say about him. Hannah and Her Sisters, Play it Again Sam, Take the Money and Run, The Front, and Manhattan. If you are not impressed by these films then watch them again in ten years. Now during those those ten years you would have to learn something about Jewish Culture, Freudian Psychiatric methods especially psychoanalysis, the Communist Revolution, classical literature and music including jazz and modern art. He can be enjoyed somewhat without knowing these things but a whole lot of what is gong on would be missed. To understand The Front you would have to know about McCarthyism and the Black List.
