Dead Poets Society preached self-pursuit, self-expression and happiness. Don't be enslaved by parents and authority, but pursue yourself bravely. It expresses empty concepts such as love, freedom, ego and art related to youth-not empty concepts themselves, but empty expressions in movies. Secondly, as far as the education method is concerned, the "new" education method used by literature teachers also contains some messy articles and no concept of unified theme, which makes the film look shallow as a whole. For example, the method of walking in the yard shows that three students should boldly go their own way and walk in different ways to exercise their rights, so that students can stand on desks and inspire them to see things from different angles, which is not well combined with the theme. The United States, which has no culture, seems to have been going against the tradition for the sake of the tradition of parade. Thirdly, the film tries to enhance its appeal with tragedy, but this tragedy completely violates the theme of the film. Since the theme is to encourage young people to pursue their own ideals, and those who do so eventually fail and lose their lives, is this encouragement appropriate? Or did the reform of literature teachers fail? Although the student's death was mainly because he cheated his parents and teachers under pressure, which led to the escalation of the conflict, it is not an exaggeration to say that the escalation of the student's inner conflict was caused by the literature teacher, and finally the school's punishment for him was not out of thin air. Before releasing students' external pressure, literature teachers simply encourage students' inner freedom and self, which will inevitably make vulnerable young people unable to face it.
