well, for me, he is one of the best actor of his generation. I always loved (and still does) the choices he made about movies, the kind of movies i like. You know, i mean he is not often chosing "block buster" movie, holywood kind, but alternative, indepedent movies, which are, i think, better movies most of the time. Plus he always get really involved in his character.
